An oscillation in pressure, stress, particle displacement or other physical parameter in a medium with internal forces (American National Standards Institute Technology).
SOUND LEVEL
The weighted pressure level, measured by the use of a metering characteristic and the weighting A, B and C (American National Standards Institute terminology).
SOUND-LEVEL METER
An instrument, including a microphone, an amplifier, an output meter and frequency-weighing networks, for the measurement of sound levels (American National Standards Institute terminology).
