Fluctuating noise definition
Fluctuating noise means a noise in which the loudness varies with time. This is expressed technically as a noise whose sound pressure level varies significantly and exceeds the ambient noise level.
Fluctuating noise means a noise whose sound pressure level varies significantly but does not equal the ambient environmental level more than once during the period of observation.
Fluctuating noise means the sound pressure level of a fluctuating noise varies more than 6 dB(A) during the period of observation when measured with the slow meter characteristic of a sound level meter.
