SOUND
An oscillation in pressure, stress, particle displacement
or other physical parameter in a medium with internal forces (American

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).

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).
