– In this video, I'm talking
about an alternative way to treat single-sided deafness, coming up. (upbeat hip hop music) Hi, guys, Cliff Olson, Doctor of Audiology and founder of Applied Hearing
Solutions in Anthem, Arizona and I cover a bunch of
hearing-related information to help make you a
better informed consumer, so if you're into that, make sure you hit that subscribe button, and
don't forget to click the bell to receive a notification every
time I release a new video. There are several
different treatment options when it comes to single-sided deafness.
You have bone-anchored hearing aids like the Baha Attract and Connect, and you also have the
ADHEAR system from Med-El, and then you have traditional hearing aids that use either a CROS or a BiCROS setup using a CROS transmitter. Each of these systems
work in a similar way. They basically take
sound from your bad ear and send it over to your good ear so your good ear can do the work and actually understand speech that's coming from your bad side. It's actually overcoming a phenomenon that we call the head shadow effect. The head shadow effect is
essentially the phenomenon that happens when sound is trying to cross over your head
into your other ear and it ends up resulting in about a six or seven decibel reduction in that sound, which can
completely destroy your ability to understand speech, from your bad side, or even make you completely unaware that anyone's even talking
to you from your bad side.
In the case that you
also have a hearing loss in your better hearing ear, these devices can be programmed to amplify that sound once it gets over to
your better hearing ear, so not only are you gonna
overcome the head shadow effect, you can also amplify
it so you can overcome the hearing loss in that particular ear. However, each one of
these treatment options tends to ignore your bad ear, and what if your bad ear has a little bit of residual hearing left in it? In some cases of single-sided deafness, you could have some
measurable hearing thresholds in your bad ear, you could
also even have a little bit of word recognition ability in that ear, just not enough to give you
complete speech understanding capabilities in that ear.
You might also have tinnitus in that ear. A lot of individuals who go
through a sudden hearing loss will be left with this
really loud roaring tinnitus that drives them absolutely crazy, and what if we could actually
stimulate that particular ear to gain some additional benefits
like binaural summation, which is the increased
benefit that you get when both ears participate in a task, or what if it could actually
mask over some of that tinnitus that you have, then it would make sense to actually amplify that deaf ear, as well as sending sound
over to the better ear.
This type of treatment
that I'm talking about, is called AMPCROS. AMPCROS is essentially a way
that we set up hearing aids in order to amplify the
side that is your bad ear and also sending that sound
over to your better hearing ear and maybe even amplifying it if that ear has a hearing loss as well. Now, AMPCROS isn't necessarily a product. It's rather a way that
a hearing care provider can set up a set of hearing devices in order to accomplish this function, and not a lot of hearing
care providers are aware of how to actually do this. An AMPCROS setup is accomplished
by taking hearing devices that have a binaural phone feature. That binaural phone
feature can then be set up to accomplish what we want it to. The binaural phone feature
originally was designed for individuals who hold
the phone up to one ear and want to send that
phone call from that side into their other ear as well, so they can hear the
phone call in both ears which increases their
It works terrific for phone calls, but you can also use it
for single-sided deafness. By using this binaural phone feature, we can essentially set those devices up to provide amplification to your bad ear and also send sound over to your good ear and if we need to, we can
amplify that sound as well to make sure that you can
hear sound from your bad side in your good ear, as well
as masking over any tinnitus or giving you any little
bit of additional benefit by providing amplification
to your deaf side.
Now, even though AMPCROS can
be a terrific treatment option for a variety of individuals
who can still get a little bit of residual
hearing on their bad side, it isn't without its shortcomings, and so it has one particular shortcoming that you have to deal with, and that is, when you actually use a phone feature instead of an automatic program setting, you're actually going to limit the amount of automatic features that you can have in those hearing devices, so
if you go to a noisy restaurant you're not gonna be able to use some of the noise reduction features of that particular hearing aid, because you're essentially
telling that hearing aid that you want it to remain
in the phone feature.
I would venture to say that
there is a number of people out there that are using a
bone-anchored hearing aid or a BiCROS or a CROS hearing aid setup that would get even more benefit
by using an AMPCROS setup. If you're someone who has a
little bit of residual hearing on your bad side, and
you also wanna be able to cross that sound over
into your better hearing ear, AMPCROS might be the right
treatment option for you. Quick shout out to Dr.
Scot Frink, who provided some of the content and
inspiration for this video. If you are someone with
single-sided deafness and you're up in the Salem, Oregon area, Dr. Scot Frink is one
of the foremost experts in our industry for single-sided deafness using CROS, BiCROS and AMPCROS. That's it for this video,
