Criteria for environmental noise based on neutral reaction of inhabitants

Abstract

According to the social survey of dose-response to environmental noise, the criteria are generally decided by noise level with the percentage of inhabitants who feel their outdoor noise to be highly annoyed.However, neutral reaction to environmental noise that occupies middle range between positive and negative reaction tends to be prevailing in usual social surveys and samples are collected efficiently.In this paper, we focus on neutral reaction of inhabitants in social surveys carried out in Nagoya City.We applied various kinds of statistical methods to the dose-response to environmental noise in order to derive the criteria.These results are compared with the ones on basis of strong or positive reaction.Moreover, we examine the stability of the criteria derived from different reactions and methods.
