The statistical method of noise measurement(II)

Abstract

The statistical method of measurement of fluctuating noise was already proposed by the author. Some numerical examinations were carried out using the data obtained by the Noise Abatement committee of Acoustical Society of Japan. The deviation of average levels due to different calculating methods and the frequency of occurence of last figures of level reading were discussed. Also the typical frequency curve of street noise level was obtained from the summarized data.
