INTRODUCTION:
When Geoff Plant asked me to give this keynote presentation,
he said to be sure that I included some of my personal experiences
as a hard of hearing person. Actually, I wasn't sure if
I could or should do this, since I don't feel all that comfortable
talking about myself. On reflection, however, it really
may be a good way to introduce a conference on Aural Rehabilitation
(AR), since I believe there are lessons we can draw for
the present day from my personal experiences a half-century
ago
My hearing loss was detected in l951 while I was in the
Air Force. I think its onset occurred during an earlier
period of military service. Of course, like just anybody
else with hearing loss, I knew I had some hearing difficulties
and, like many other people in the same predicament, I simply
tried to ignore its presence, getting along as best I could.
At the time, the only help I would have considered would
have been medical or surgical -- some way to "cure"
or "fix" my hearing loss. Fortunately for me,
I was not given a choice.
After I was given an audiometric test, which clearly revealed
the presence of hearing loss, the next thing I knew I was
transferred to Walter Reed Hospital, as an involuntary participant
in their AR program. But not before the examining otolaryngologist
told me that I had "progressive hearing loss"
and that I would soon be going "deaf!"
It was only many years later that I realized the doctor's
definition of "deaf" and my definition of "deaf"
were quite different. Without
hearing aids, I would indeed be "deaf", but
certainly not with them. From my perspective, the only definition
of "deaf" that counted was my ability to use audition
as my primary communication mode. The fact that I can still
do this, even with a bilateral 90 dB hearing loss, tells
me that I am not functionally "deaf". That doctor
did me, and I'm sure many other patients, a great disservice
when he employed a term in one way that most people would
understand in a different way. Simply said, his comment
scared the hell out of me and this fear stayed with me for
many years, until I learned better.
In any event, the Air Force gave me no opportunity to object
to the transfer, or to engage in the usual and agonizing
self-defeating exercise of denial. Ironically, it now appears
that one of the merits of this entire process may have been
the fact that I did not have a choice: being in the military,
I was simply ordered to go and I did. In my case, there
was not the usual seven-year delay between the symptoms
of a hearing loss becoming apparent and the acquisition
of hearing aids. Clearly,
the military model is not a model we can follow in civilian
life, however we might sometimes wish it.
The Walter Reed AR program lasted for two months, during
which time the participants were all boarded together in
a separate facility. All day every day we went to various
classes, ranging from general information about hearing
loss to speechreading and auditory training. At the beginning
of the program we were issued hearing
aids selected for us by the traditional Carhart procedure
(an early hearing aid selection
protocol). We were each tested with about four to six aids,
trying to determine which one was "best" for us.
The measures included unaided and aided speech discrimination
tests in quiet and in noise, comfort and uncomfortable determinations,
and both use and full gain aided speech reception threshold
(SRT) tests. "Best" was defined in terms of higher
speech discrimination scores, wider dynamic range, lower
aided SRT's, and subjective preferences. Cosmetic preferences,
as can be imagined, never came up.
This test battery would take almost a complete morning
or afternoon. Even so - that was not the end of the process.
About once a week, I returned for follow-up testing and
such "fine-tuning" as could be done in those days.
Complaints and problems with the
hearing aids and earmolds were handled almost immediately.
However, it is important to note that unlike today, where
the provision of hearing aids
is often considered the end point, in my AR program, the
hearing aid was just one component of a comprehensive
AR program.
The formal program was supplemented by many "bull-sessions"
and informal exchanges between and among clients that took
place during, in-between, and after classes. Although we
did not use the term "coping and communication strategies",
that was in essence, what was going on. We shared our hearing
experiences, some of our feelings (being "macho"
young men we didn't delve too deeply into ourselves) and
examples of what kind of communication tactics worked and
did not work. Actually, in retrospect, these experiences
were probably the most valuable aspect of the program. The
group interactions provided the kind of emotional support
impossible to replicate in individual counseling sessions.
This is definitely a lesson that we can take to heart even
now.
Although we thought we were learning to lip-read and how
to make better use of our residual hearing, and some of
us undoubtedly were, what was also happening was that we
were learning how to accept the hearing loss and accept
ourselves. We would joke with one another about "being
on the air" when we put our
hearing aids on and, by example, encourage those who
were reluctant to wear them. Unlike the pressures new hearing
aid users often feel that can lead to them to discard
their hearing aids ' feeling
"different", stigmatized and a bit ashamed - the
social climate in the AR program was exactly the opposite.
It was expected that everybody would "conform"
to the accepted practice by regularly wearing his hearing
aids. The fact that the program lasted for two months
made it easier to continue our good hearing
aid habits after we left.
The hearing aids we were
issued were monopack vacuum tube hearing
aids, requiring an "A" battery that had to
be changed every two or three days and a "B" battery
that would last a week or two. We felt very lucky to be
the recipients of these "small" convenient instruments,
particularly since the groups who preceded us were issued
duo-pack hearing aids; those
required a battery pack physically separate from microphone
and amplifier. Besides, being in the service, we could hardly
insist on receiving more "cosmetically acceptable"
devices. First, because this kind of demand was simply unheard
of in those days, and second, cosmetic concerns, even if
we could conceive of how far down the ear canal it has taken
us nowadays, was simply not an issue. We wore what we were
ordered to wear, based on professional judgment regarding
what was considered "best" for us. Nowadays, unfortunately,
professional judgment regarding performance often takes
a distant back seat to a patient's expressed cosmetic concerns.
After the AR program, I spent three years in the Air Force,
spending much of that time in North Africa where, I believe,
I may have been the only person wearing hearing
aids, if not on the entire continent, at least in the
immediate region. There's another, very important lesson,
here for the present day: Because I accepted the fact that
I had to wear hearing aids,
and accepted myself on this basis, I truly believe the presence
of my hearing aids was completely
irrelevant as far as my work and social activities were
concerned. I didn't make a big deal about the fact that
I wore hearings aid and consequently,
neither did anyone else. If somebody asked about it, I simply
said it helped me hear like eyeglasses help someone see.
I can't think of a time when this explanation did not suffice.
I've never accepted the notion that wearing a visible hearing
aid is associated with a negative personal appraisal,
some kind of social stigma invoked by society on hearing
aid users, or what has been termed the "hearing
aid effect". Of course, I do know that some people
in our society may initially judge hearing aid users as
less competent and less desirable, etc. But, I'm convinced
that, given self-acceptance, their attitudes will soon either
be irrelevant or changed. Instead of confronting this presumed
"stigma", however, we pander to it by focusing
on cosmetics rather than performance and need.
I should point out, however, that even with the exemplary
Walter Reed program, I must have still felt a great deal
of uncertainty about how the hearing loss was going to affect
my life. Given the initial diagnosis of "progressive
hearing loss", I was understandably insecure about
the future. When I returned to the U.S. from North Africa,
I asked to be transferred to Walter Reed hospital so that
I could take the AR program once again. To its credit and
to my benefit, the Air Force agreed to my request.
In a sense, what I was asking for was an AR "booster"
shot. Even more than my first experience, I believe it was
at that time that I truly came to terms with the fact that
I had permanent hearing loss. It was at that time that I
accepted the notion that while its presence was clearly
going to produce some difficulties in my life, the fact
that I was hearing-impaired need not restrict the course
of my life in any fundamental way.
There are lessons we can draw from this for the present
day. Just because we have, or think we have, provided what
we believe to be an appropriate AR program to our patients,
that does not mean that they will thereafter be "cured"
and never darken our doors again. As we well know, it doesn't
work that way. We know that people's hearing loss and their
communication needs change over time. We know that much
of what we covered and what we thought we had resolved initially
may have been forgotten. And we know that new devices and
techniques are constantly being introduced, which may offer
benefits previously unavailable.
Our clients often need a "booster" shot from
us, a provision that should necessitate a routine follow-up
program.
The "Stigma" of Wearing
Hearing Aids
Majoring in "Speech and Hearing" when I left
the service brought about a whole new set of lessons that
have stayed with me. Actually, the primary reason I started
college was to learn enough about audition and hearing
aids to be a knowledgeable hearing
aid salesman. So for the first year I was at college
I sold hearing aids part
time. In all that time, I sold just one aid, and only because
one of my brothers arranged the sale! I worked by knocking
on the doors of people who had made some sort of inquiry
in the past. Their responses really exposed me to some of
the attitudes about hearing loss that pervaded our society
then and, to a large extent, now. People would deny they
had hearing loss while I had to shout at them to be heard!
Or they would be very upset that I somehow knew about this
terrible secret of theirs. After all, they were promised
when they responded to an advertisement that they would
be sent material in a plain brown envelope, so nobody would
know they inquired, and that no salesman would come knocking
at their door. And here I was exposing their shame and stigma
for all the world to see!
Salesmen were advised to stress how small and invisible
the hearing aids were. These,
we should note, were body aids! All kinds of tricks were
played to minimize visibility, from transparent tubing that
ran from the earmold to the receiver pinned under the collar,
to beret style aids that were placed in the hair. Fifty
years later, we're still doing the same thing. It doesn't
matter how technically advanced
hearing aids have become, or how tiny these really sophisticated
devices are; they're still not sufficiently invisible for
many people. And for some, they will never be small enough.
It's clear that the problem is not the visibility of the
hearing aids, but rather the acceptance of the hearing
loss. In the fifty years that I've been involved with this
field, we are still communicating mixed messages. On one
hand, we justifiably stress the technical advances incorporated
in modern hearing aids. At
the same time, however, we emphasize how tiny they are,
how they can fit all the way down in the ear canal and that
nobody "need know they're wearing
hearing aids."
What is happening is that we are reinforcing the very denial
attitudes we are trying to overcome. By stressing invisibility,
we convey the message that there is something shameful about
hearing loss, that it is a stigmatizing condition that people
must disguise as well as they can. I'm convinced that more
potential hearing aid candidates
are discouraged from trying needed amplification by this
type of appeal than are motivated to try them by the cosmetic
arguments. People don't "hear" the cosmetic appeal
as loudly as they do the underlying shame and stigma message.
If we can't get people to acknowledge that they have hearing
loss, there is nothing we can do to help them. Clearly,
they are not ready to help themselves. One measure of our
success in this endeavor would be the percentage of people
who can potentially benefit from amplification who actually
wear hearing aids. In this country, that figure is usually
considered to be about twenty percent - not a very impressive
record.
Taking Hearing Loss Seriously
In order for this percentage to increase, there has to
be more awareness
regarding the potential consequences of hearing loss, that
it can, and often does, impact on every aspect of a person'
life. However, instead of some measure of empathy, what
we often get are insensitive comments like "she can
hear if she only pays attention".
If society underestimates, mocks or trivializes the total
impact of hearing loss then it is unlikely that any type
of AR program will be supported or encouraged. The condition
would not be considered a severe enough public health problem
to warrant public resources allocated to its remediation.
At a time of limited resources and rising expectations,
such an understanding is crucial if AR is to receive its
justified portion of the health-care pie.
If we only had to convince the general public and policy
makers regarding the potential implications of a hearing
loss, and the need for AR services for most people with
hearing loss, then our challenge would be straightforward,
if not easy.
Unfortunately, it seems to me that before we educate others,
we need to start by educating ourselves.
The hearing aid selection
and dispensing model most often employed by hearing aid
dispensers focuses on the instrument - the
hearing aid itself, rather than the person with hearing
loss. In the ordinary sequence, a client first receives
an audiological evaluation, then
the hearing aid is selected
and several follow-up appointments are scheduled.
In the current hearing aid
dispensing model, the average total time devoted to all
of the activities associated with the hearing aid acquisition,
from the initial testing and personal interview to the actual
selection, fitting, follow-up and counseling is little more
than two hours (Stika and Ross, 2001). Less than an hour
is spent on the counseling component (Kochkin, l999). Perhaps
the current model provides sufficient time for these activities.
But there certainly will not be time to deal with other
personal and social issues arising from hearing loss. The
current hearing aid dispensing
model implies that all hearing-impaired people need to correct
their problem is an auditory prosthesis, i.e., a
hearing aid. This is clearly not the case.
The fact that people want and need more information can
be seen in the marketing survey prepared for the AAA (Audiology
Today, l998). Almost half the hearing-impaired people who
responded to the survey reported they would have liked more
information on how to select, wear, and care for
hearing aids. About forty percent of them wanted to
learn more about the causes and treatment options for hearing
impairments. Even this relatively high number probably underestimates
the number of people who could use and benefit from such
information.
It is not as if there is any real dispute among professional
audiologists regarding the consequences of hearing loss.
Indeed, there is also an enormous body of literature on
this topic, much too much to review in any detail here.
For example, Carren Stika reported the results of the many
focus groups she conducted with hard of hearing people and
their significant others (Stika, 1997a;l997b). The fact
that hearing loss can have a pervasive and profound effect
upon the affected person and his/her family was clearly
demonstrated in this project.
Implicit in the current hearing
aid dispensing models is the assumption that the provision
of hearing aids are both
a necessary and sufficient response to the hearing loss
condition. This model implies that hearing
aids can functionally "cure" the hearing loss
and that further services are either unnecessary or not
cost effective. We would all agree that
hearing aids are an absolutely necessary measure to
take in most instances of hearing loss. However, I would
hold that for most people, hearing
aids alone are insufficient.
Of course hearing aids help,
and of course most people, comparing their ability to function
with and without hearing aids,
do better with them than without them (Kochkin & Rogin,
2000). No doubt, many people would believe, at least initially,
their hearing problems have been "solved" or at
least rendered functionally irrelevant by the
hearing aids. Not knowing any better, they accept less
than is possible and live with the resulting limitations
and problems while enjoying the benefits. This is not good
enough. We can do better.
For example, about 16% of people eventually stop wearing
their hearing aids, and a
similar number rate their hearing
aid usage as unsatisfactory (Kochkin, 2000). Satisfaction
percentages seem to hover somewhere between 60 and 70 percent.
Importantly, we know that additional counseling and follow-up
programs can reduce the number of returns and increase benefits,
use, and satisfaction rates (reviewed in Ross, 1999; Kochkin,
1999). Indeed, a number of papers explicitly address the
organization, advantages, and cost effectiveness of AR procedures
that go beyond merely providing hearing aids or cochlear
implants.
'
Services and Information Needed by Hearing
Aid Wearers
Let's consider the services that hearing-impaired people
require when they finally arrive at a hearing
center. It is important to keep in mind that we would
not be seeing these people if their hearing problems had
not, somehow, become personally intolerable or if they had
not finally succumbed to repeated nagging from some significant
other.
What, then, are our professional obligations to them' The
ostensible reason they come to us is for professional advice
regarding hearing aids. And,
of course, the proper selection and instruction in the use
of hearing aids still has
to be a paramount consideration. The implicit reason they
see us, however, is not for hearing
aids per se, but because they want help in minimizing
the hearing-related problems they are experiencing. Well-selected
hearing aids are just one tool, albeit the major one,
that addresses this issue. There are other services and
information we can provide that will help people reduce
the total impact of hearing loss on their lives. The clients
may not be aware of these other services, but shouldn't
it be a professional responsibility to make these services
known to them' What I am suggesting is a focus not on a
product, but on the rehabilitative process. It is when patients
show up at our door asking for help with hearing
aids that we have the best opportunity to address the
totality of their hearing-related problems. So what services
am I talking about'
All prospective hearing aid
users require a comprehensive audiologic evaluation. This
may sound self-evident, but what with
hearing aids being sold through mail order and the internet,
it cannot be considered a given. A component of this evaluation
should be devoted to an extensive personal interview.
Either preceding or immediately following the personal
interview and audiologic evaluation, the client should have
an opportunity to complete some type of standardized self-assessment
scale. The same scale should be administered after the person
has worn hearing aids for
some time. In a recent chapter, Abrams & Hnath-Chisolm
(2000) provide a comprehensive discussion of outcome measures,
with examples of the different types that can be used for
different purposes. Their rationale extends beyond providing
data regarding therapeutic effectiveness and institutional
accountability. Responses to self-assessment scales can
help guide the nature of the therapeutic process. '
Many, perhaps most, people with hearing loss can benefit
from a group hearing aid
follow-up program. The follow-up program is to supplement,
not supplant, individual counseling. This gives clients
an opportunity to review and share their listening experiences
with other people with hearing loss. The mutual support
people give each other transcends that which professionals
can provide. Some topics, such as advantages of binaural
hearing aids, can be covered more convincingly when
someone else in the group relates personal experiences,
rather than when the recommendation appears to be tied to
a dispenser's self interest. Reluctant hearing
aid users, or those who feel that "it is just too
much" trouble can be encouraged appropriately by their
peers and colleagues.
People need general information regarding the cause of
hearing loss and treatment options. People deal with problems
more effectively when they have a greater understanding
of its nature. Many people come to clinics wanting and expecting
to be "fixed" medically or surgically. They have
to understand why some types of hearing loss are not amenable
to such treatment and that the best single "treatment"
is often a well-functioning hearing
aid.
People need information about the listening implications
of their own audiometric results (for example, why so many
people seem to be "mumbling", and why they can
often "hear" but not "understand").
This is the kind of topic that dispensers tend to gloss
over after the 1000th time they explain it to clients. It
is difficult, but necessary to provide such information
each time, as if it were the first time. '
The "significant others" in each person's life
should understand the communication implications of their
loved one's hearing loss. By listening to others make complaints
similar to their loved ones, they can more fully appreciate
the problems. One useful technique is to play a tape of
filtered speech to the normally hearing significant others.
'
People need information regarding how to care for their
hearing aids and
earmolds. They need to know why one type of
hearing aid was selected rather than another. This leads
to a discussion of the particular features of their own
hearing aids, what they do, and why they were included
(e.g. directional microphones, T-coils, presence or absence
of volume controls, personal FM capability, direct audio
input, multi-bands, multi-memories and so on). This kind
of information takes time to convey and group presentations
can supplement individual instruction. '
A group setting lends itself to help people develop realistic
expectations of what hearing aids can and can't do. Some
people's expectations may be unrealistically high, while
others set theirs too low. People have to understand what
hearing aids can and can't do. This discussion leads naturally
to the topic of other types of hearing assistive devices.
'
The evaluation and dispensing of other types of assistive
listening devices (ALDs) is, in my estimation, one of the
biggest weaknesses in present
hearing aid dispensing practices. For some people, specific
ALD devices can significantly improve their quality of life
as well as directly impact upon job performance. Virtually
everybody in our society is required to use a telephone
and importantly, telephone communication can be improved
for almost every person with hearing loss. Virtually everybody
watches TV, goes to the movies, attends lectures or concerts,
or visits houses of worship. In each of these venues, it
is possible to improve listening comprehension with an assistive
listening device. Some people will function better on the
job if they can use a personal FM, a conference microphone,
an amplified telephone, or a vibrating pager. The need for
such devices may not be immediately apparent; it requires
an explicit evaluation to make this determination.
People with hearing loss can benefit from information about
various kinds of communication and repair strategies that
can be used to enhance interpersonal communication. This
should include a presentation and discussion of the basic
principles of speech reading. With a little practice and
focus on the lips and face, hearing-impaired people can
improve their comprehension of the spoken word. They should
know about the concept of assertiveness, when and where
it would be appropriate, and encouraged (via "homework")
to practice it in their everyday lives.
Finally, even after receiving the services specified above,
many people with hearing loss still need the continuing
support of others in similar circumstances. The astute audiologist
will keep an open channel to a local chapter of Self
Help for Hard of Hearing People, Inc. (SHHH) and make his/her
clients aware of the potential contribution of this consumer
support group.
Does everybody with hearing loss require all of the above'
Probably not. But we should begin, with the clinical assumption
that anybody who needs hearing
aids to improve communication functioning can benefit
from most of them.
The record in this regard is mixed (Stika & Ross, 2001).
The key limitation is time -and how to find it. It takes
time to listen to our clients and to deal with communicative,
as well as the psychosocial implications of hearing loss.
It takes time to conduct a group hearing aid orientation
program. It takes time to evaluate the need for and to provide
assistive listening devices. And it takes time, particularly
for older people, to work through
hearing aid fitting procedures until they reach the
point that they are receiving the full benefits of hearing
aid amplification. As we keep hear over and over again,
"Time is Money," and importantly, where do we
do find the money to pay for the time'
'
Redefining the Hearing
Aid Selection Procedure
The first thing we have to do, I believe, is change the
way we think about the hearing
aid dispensing process. We can't rediscover Camelot,
the AR program that I experienced fifty years ago is gone.
Like the original Camelot, it has faded in the mists of
time; an idealistic dream of perfection that we know can
never be recalled. Still, as much as I personally enjoyed
and benefited from the program, I do think much of it was
overkill. When all this began during WW II, there must have
been a great deal of insecurity about what newly deafened
servicemen needed. The decision must have been to give them
everything, growing out of a concern that otherwise some
vital element would be omitted.
We can't do "everything" nowadays; choices have
to be made. I believe we can do a credible job within the
present system if we incorporate some of the lessons from
the past.
The most important of these lessons is that we must conceptualize
the selection and dispensing of
hearing aids within a larger framework. While it may
sound like a cliche we do have to keep in mind that we are
not working with a pair of ears but with the person to whom
the ears are attached. We should view the hearing
aid fitting as an opportunity to explore a number of
hearing-related issues and to help the hearing-impaired
person deal with them. We must, in brief, redefine the
hearing aid selection process in a way that it routinely
incorporates a multi-session group
hearing aid orientation, or short-term AR, program (Ross,
1999). I hasten to point out that this is not an original
concept by me; it has been recommended, written about, and
practiced by many of our colleagues, many of whom are now
attending this conference.
I do believe that such a program should not be optional,
but simply be included as a routine component of the
hearing aid dispensing process. For the same reason
we would not think of fitting someone with a hearing
aid unless a prior audiological
evaluation was conducted, we should not fit hearing
aids without an organized follow-up program. This is
based on my assumption that the overwhelming majority of
people acquiring hearing aids
for the first time need the kind of services and information
outlined above. By separating these services from the
hearing aid itself, by referring only some of our hearing
aid clients to an organized follow-up program, we send
a message that only exceptional
hearing aid users require and can benefit from such
a program.
On the contrary, I believe we should send the opposite
message, that a hearing aid,
while certainly the centerpiece of the aural remediation
effort, is only one of the tools used to reduce the communicative
and handicap impact of hearing loss. What this implies is
that the expenses of the short-term AR program be included
in the cost of the hearing aids
(Ross and Beck, 2001).
In summary, our current management model tends to minimize
the total impact of hearing loss. Most people can use and
benefit from the additional services a short-term aural
rehabilitation program can provide. Such a program can be
most efficiently and conveniently included in association
with the acquisition of hearing
aids. In this respect, the lessons from the past are
very clear. If only we "listen" to them.
