aircraft (including, but not limited to:
altitude, temperature, noise conditions,
unpressurized aircraft, etc.) resulting
in possible interference to critical
communications.
The Occupational Safety Health
Administration (OSHA) has issued
headphone usage recommendations
for maximum daily exposure and sound
pressure levels (measured in decibels (dB)).
A decibel is a unit of measure of sound, and
decibels increase exponentially as sound
gets louder. For example, conversational
speech is typically around 60dB, and a rock
concert in a stadium is often about 110dB.
