抄録

The summarized results of measurements of city noise in Tokyo are reported. The first measurement was carried out from 25th to 28th Nov. 1952, at the most noisy area in Tokyo; from Hibiya to Tsukiji. Average values and distribution of noise levels at 48 places from 8 a. m. to 9 p. m. and at 5 places from morning to the next morning were obtained. About one hundred observers belonging to twenty-one government and civil organizations took part in the measurement. The second one which was about the same scale as the first, was held from 25th to 27th Feb. 1953, at seven typical areas; Marunouchi, Kanda, Shinjuku, Shibuya, Hongo, Ueno and Asakusa. The main results obtained are as follows: (a) Variations of noise level during 24 hours are shown in Fig. 6-10, (b) Noise levels during the day; Fig. 11-18, (c) Distribution of noise levels at different areas and different street conditions are summarized in Fig. 19-21, (d) Noise from vehicles and their horns; Fig. 22, 23 and 25.
