Objectionable noises due to intermittence, beat, frequency or
shrillness shall be muffled so as not to become a nuisance to adjacent
uses.
|
At the specified points of measurement, the sound pressure level
of noise radiated continuously from a facility shall not exceed the
values given in Table A in any octave band of frequency. The sound
pressure level shall be measured with a sound level meter and an octave
band analyzer that conform to specifications published by the American
Standards Association. (American Standard Sound Level Meters for Measurement
of Noise and Other Sound, 224.3-1944, American Standards Association,
Inc., New York, New York, and American Standard Specification for
an Octave Band Filter, Set for the Analysis of Noise and Other Sounds,
224.10-1953, American Standards Association, Inc., New York, New York,
shall be used).
