Gun Noise and Ear Damage
Comparing gun noise with other common noises. The left column is the noise
level measured in ("db") the right column is noises around us. The db
scale is logarithmic, level 2 is twice as loud as level 1, level 60 is
twice as loud as level 59. The average siren is about 110 db at 10 feet this
will start to damage the unprotected ears after 45 minutes.
Therefore it is easy to understand that even one gunshot at 140db is injurious of unprotected ears.
||The quietest sound you can hear
||Whisper, quiet library
||Normal conversation, sewing machine, typewriter
||Lawnmower, shop tools, truck traffic, 8 hours per day is the maximum
exposure (protects 90% of people)
||Chainsaw, pneumatic drill, snowmobile; 2 hours per day is the maximum
exposure without protection
||Sandblasting, loud rock concert, auto horn; 15 minutes per day is the
maximum exposure without protection.
||Gun muzzle blast, jet engine; Gun noise causes pain and even brief exposure
injures unprotected ears. Maximum allowed noise level with hearing protector.
When shooting it is always preferable to use some kind of ear
protection. During sustained shooting the shooter should use double protection,
i.e. ear plugs and ear muffs because ear plugs do not always protect fully at
these pressures. Ear plugs and muffs are available at any gun shop, most
hardware and home building materials retailers tools sections. Remember
Hearing aids are a nuisance and never work very well - save your ears because
once gone silence is forever.
If you do experience gun noise to the extent that it leaves your ears ringing
for more than one hour you should seek an Ear Nose and Throat specialist (ENT) with
a specialty of
neurotology or otology immediately. You may have a 50/50 chance of regaining
full hearing with his medical treatment. Immediate treatment is necessary if
full recovery is desired.
Loud noise ear damage is accumulative add
to other exposures all around and you can assure the need of a hearing aid at an early age.
