The
RNID
runs a campaign for raising awareness
of hearing damage among young people. This campaign is called
Don't
Lose the Music and offers advise on protecting your hearing.

Ever thought
about your hearing?
Something we all
take for granted day to day.
How many of us
walk past workmen using a pneumatic drill and cover our ears?
That's because
it hurts our ears and our natural instinct is to prevent our bodies from
feeling pain.
So a pneumatic
drill is around 110 dB and we are agreed that causes a degree of
pain, where do you go at the weekend?
How loud
do you think it can get in your favourite club?
The RNID (Royal
National Institute for Deaf People) has found that noise levels in
nightclubs range from 90 to 109 dB.
How long do you
stay in your favourite club? 4 hours approx?
Let's see how
that affects your ears, as you can see even at 91dB the safe listening
time is 2 hours. So 2 hours at 91dB is the equivalent of 8 hours at
85dB.
85dB is a
threshold set by
The
Health and Safety Executive but these regulations only apply to work
situations, not your social life. So it is up to us to safeguard
ourselves.

Sound pressure is based on a logarithmic scale and expressed in Decibels
(dB). Each time the decibel level is raised by 3(dB), the intensity of
that sound is doubled, in other words it is twice as loud. When the
intensity is doubled, the safe listening time is halved. The table below
shows how quickly safe listening times are reduced as the sound level
increases.
What damage is
being done?
Many of us
suffer short-term hearing problems after being exposed to loud noise
over the course of an night out. This is often dullness in the hearing
or ringing / buzzing in our ears. This is a warning that we have
exposed our ears to too much noise and gradually improves within a day
or two. If after 48 hours your normal hearing hasn't recovered, then you
should visit your GP.
Diplacusis: A difference in the pitch perceptions of the
two ears when stimulated by the same sound frequency.
Hyperacusis: A condition characterized by an
over-sensitivity to certain frequency ranges of sound which may cause
discomfort or physical pain.
Tinnitus: buzzing, ringing or tone in the ear without an external
cause. You may experience tinnitus in one or both ears or in the head.
Temporary tinnitus is a warning, you may not be so lucky next time!
What can we do?
Part of the
problem is that if you are in a club or listening to your headphones
after about an hour your ears get used to the level, so you turn your
headphones up or move closer to the speakers. This is where the damage
starts to happen. If you were to turn your headphones off for 5 - 10
minutes or move to a quieter room in the club you would be giving your
ears a rest and the level would not need to be increased on your return.
The same applies
to front of house engineers, after around an hour the engineers ears get
used to the level and starts pushing the system because he feels that
the volume has dropped. That's why intervals are useful, not just for
refilling your glasses but to give everyone's ears a rest. Next time
your at a gig after the interval watch the engineer will he reach for
the master faders? will he look around thinking someone has turned his
master faders up while he was in the loo?
One of the best
ways to prevent damage is to wear ear plugs.
I know, you
think that ear plugs would defeat the object of hearing the music in
fact this is not the case. The
RNID recommend
spending up to £14 for a pair of re-useable plugs. They 'closely
replicate the ear's natural frequency response' which in plain English
means it sounds as if the volume has been reduced. Some people have told
them they actually make gigs sound better because they filter out the
distortion - and you can even hear the vocals over the guitars.

But you think it
would be uncool to wear ear plugs at a club or gig. What's uncool
about protecting your hearing? When the sun comes out we protect our
skin and our eyes, when we ride our bikes we are sensible enough to wear helmets. So why are we
not doing the same for our ears?
We need to
forget about the image or coolness of ear plugs and start protecting
ourselves. No one else is going to do it for us, music venues and clubs
may start to do all they can to reduce the risks but it is still our
responsibility.
At the end of
the day we all need to think whether we want to be able to enjoy
listening to music into our later years, or listen to the ringing in our
ears or even worse not being able to listen at all.
