Draft, Review & Redline at the Speed of AI

Noise level means the “A” weighted sound pressure level in decibels obtained by using a Sound Level Meter at slow response with a reference pressure of twenty (20) micropascals. The unit of measurement shall be designated as “dBA.”

Noise level means the reading on an integrating impulse sound level meter taken at a measuring point in the presence of any alleged disturbing noise at the end of a total period of at least 10 minutes after such meter was put into operation, and if the alleged disturbing noise has a discernible pitch, for example, a whistle, buzz, drone or music, to which 5 dBA is added.
