Analysis of response of workers to acoustical environments in daily life

Abstract

Survey of personal noise exposure and response to noise environments in daily life of 142 workers has been done in and near Nagoya city. In this paper, the relationships between response of workers to their acoustical environments and various factors such as age, sex, occupation, noise exposure in each place(L_&lteq&gt)and so on, are discussed. The response and other variables(i. e. factors)are properly categoralized and analyzed by quantification theory(type II and III). The results obtained are as follows;(1)Response to noise in workshop is strongly correlated to L_&lteq&gt(noise exposure during work)and occupation(contents of work). (2)Response to noise during commuting is closely related to the means of commutation and is severe to public transportation(subway, train, and bus). (3)Response to noise in residence is considerably effected by type of housing, member of family and area of residence. (4)The significant factors to determine the response to noise around residence are conditions of road and areas near by house. (5)There are close cnnection between occupation and acostical environment in daily life of workers. (6)Response to noise is severe in elder generation and female in general.
