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). |
