                                  The number one complaint hearing aid
                                  wearers have today is that their aids
                                  don’t work well in noisy situations.

                         In past articles, we explained why it is
                         so frustrating to understand in
                         background noise and, how the
                         anatomy of one’s hearing system
determines how well one will hear in noise.

Let’s discuss the part that technology plays in helping you to hear
better in noise. With the exception of advanced digital
technology, most other hearing aids turn down loud sounds but
do not really enhance speech when in a noisy environment. Even
the most sophisticated hearing aid circuits are still electronic
devices that decide what noise is and what is speech.

In these circuits, steady state sounds such as an air conditioner
running or traffic noise are interpreted as noise, and are then
turned down. Temporal sounds such as a person talking or the
sound of a plate being placed on the table are interpreted as
speech, and are turned up.

Ironically, some of the most irritating background noise can be
the babbling sounds of other people talking. Think about the last
time you were in a noisy restaurant. Other people talking
probably interfered with the conversation at your table. Although
some hearing aids will turn down these sounds in a restaurant,
they will not necessarily make the person you want to listen to
easier to hear.

This is where directional microphones come in. Directional
microphones actually turn down sounds in back of you making
the speech in front of you easier to understand. Here’s how they
work.

In general, two microphones are built into the hearing device.
One microphone is placed towards the back and the second
microphone is positioned towards the front of the hearing aid. In
quieter situations, both microphones are activated so that you
can hear all around you, in front, in back and at the sides.

But let’s say you go to a noisy restaurant and know that you will
have difficulty following the conversation at your table. You
request a table where you can place your back to the background
noise.

This is extremely important. The people you want to hear should
be facing the noise, ideally with their backs towards a wall. With
the flip of a switch, you turn off the back microphone which
quiets down the sounds coming from the back. Only the front
microphone is on, enhancing what’s in front of you – the
conversation you want to follow.

People have been amazed at how much this small enhancement
helps them enjoy conversations in difficult listening situations.
They actually feel part of the conversation instead of sitting there
like a bump on a log. Of course, every person’s hearing is unique
and the benefits of this technology vary by degree of loss, and by
individual.

Directional microphones were originally built into the most
advanced digital circuits giving you the benefits of both digital
and directional technology.

However, the good news is that directional microphones can also
be built into less sophisticated circuits. For those people unable to

purchase top-of-the-line hearing instruments, you can still benefit
from directional microphones. With a flip of a switch, you can turn
down the sounds in back of you!

Directional microphones have improved! “Automatic adaptive”
directional microphone systems have taken directionality to a
whole new level. Even when the source of noise is coming from
different directions, this automatic microphone system detects
the source and reduces the noise from that direction so that
speech is at its best. When the noise moves or changes direction
this superior microphone system follows it.

Imagine having a conversation with your neighbor when someone
starts up a lawnmower. Then, several cars drive by. With regular
hearing aids, the noises would drown out the conversation.
However, this automatic, adaptive system tracks the traffic noise
and lawnmower, automatically adjusting to give you the best
speech signal possible.

So if you’ve been putting off getting help because of so many
people’s bad experiences with hearing aids, it’s time to schedule
an appointment for a hearing test and consultation. Be sure to
get a Speech-in-Noise test and find out if directional microphones
could make communication easier for you and your loved ones.
