One of the first places that my patients report having
difficulty with their hearing is while watching television. When I was a kid
television certainly is not what it is now. I remember our black and white
television with a tiny screen and rabbit ears. My kids would find this concept
beyond foreign. My new tablet probably has a bigger screen than our old
television. The sound produced by those old sets was also fairly poor even
though some of them were built into those massive stereo systems that you might
have considered big enough to bury someone in. Today’s televisions are huge
with huge pictures connected to massive surround sound system and yet they can
still be hard to hear. In actuality they may not be hard to hear but more
specifically it may be hard to understand what is being said.
What we know about hearing loss is that for noise exposure
as well as the aging process it is the high frequencies that deteriorate on us
first. The high frequencies would be what we know as the treble sounds versus
bass. With typical hearing loss we loose sharpness before volume. When we watch
television with t hearing loss we often try to turn up the volume to help us
understand speech better however it is the clarity that we struggle with and
turning it louder does not make it any clearer and yet we still try. In reality
turning it louder can potentially further distort the sound.
Beyond our hearing ability there are other variables that
make television listening more difficult. In the “old days” the television shows
we watched were more dialogue based with music and sound effects interspersed
on a minimal level. What we watched were shows with people talking. Given the
size of the sets we also sat closer to them. In todays world the television
shows we watch are like watching action movies in the theater with sound
effects constantly where dialogue is embedded in in competing noise making it so
much harder to understand. Our television sets are so large that we sit in the
back of our rooms to watch television. Our surround sound systems are wonderful
for the sound and fury of the television shows but often the systems are not
set up correctly to allow for a focus on speech.
Here are some things that can be done to help hear
television better. While hearing testing and hearing aids may be the best
solution here are a few other things that can be done as well. If you are
watching a television set that has built in speakers go into the audio menu and
turn up the treble and turn the bass down to create a clearer sound instead of
a louder sound, this will be far more useful than volume. The same kind of
approach should be taken in adjusting your surround sound system with a
priority given to the center channel and the higher frequencies that make
speech understandable. It may be a good idea to sit a little closer to your
television as when you cut the distance in half you double the volume according
to the physics of acoustics. Another great solution is a wireless set of
earphones that give you a direct sound from your television without the ambient
room noise and which you can control the volume for yourself independent of the
others in the room.
As I have said before television is often one of those
things that allow us to see the possibility of hearing loss, as we have to directly
compare our sound levels with what others prefer. While the strategies I
outlined are wonderful ideas to help compensate understanding your hearing
needs and your hearing loss should be your starting point.
