ENGINE NOISE
Jet engine noise can cause temporary or permanent
hearing
loss.
Hearing
loss
occurs
when
your
unprotected ear is exposed to high sound intensities for
excessive periods of time. The higher the sound level,
the less time it takes to damage your hearing. Without
ear protection, persons exposed to sound intensities
above 140 dB (decibels) for any length of time may
suffer serious hearing damage. You must wear proper
ear protection at all times. You should wear double
hearing protection when working around turning
aircraft.
As
an Airman, you must be familiar with all
aircraft general safety precautions as well as those
peculiar to your squadron. The life you save may be
your own.
