Community noise was measured in the whole area of an inland middle-sized city T (population, 210, 000), situated in the south-middle part of Gunma Prefecture, and variation in its feature by difference in quarter and inhabitants' responses were investigated, with the following results: 1) Noise was largest in the central business quarter, followed by the intermediate residential quarter, and smallest in the peripheral rural quarter. Even in the latter two, noise was as large in the traffic crossing area as in the first. It is, therefore, insignificant to make uniform jurisdictional assessment of noise. 2) As for noise levels along the main roads, it was largest in the suburban zones along' the highways, followed, in the descending order, by the central business street, the street in front of the railway station, and the streets near the girls' high schools. The principal source of noise in these parts was road traffic (especially by heavy trucks). In the central business quarter, commercial broadcasting was also a significant causative factor. 3) Inhabitants' complaints against community noise had intimate relation with the trait of noise specific of the quarter. Especially there was high correlation between percentage of complaints and the upper limit of 90 % range in noise level, suggesting the necessity of reexamination of assessment by the median value of the current environmental standard. In the whole area of the city, the chief source of noise was the road traffic. This point should be taken into consideration for the establishment of the noise control area.
