Motor Vehicle Noise-Identification and Analysis of Situations Contributing to Annoyance

An interview survey of 1200 respondents in three cities identified 12 vehicle type/noise source/operating mode situations causing various degrees of annoyance. Each situation was assigned to one of three categories of annoyance sensitivity depending upon the attitudinal factors related to the source. Each category had a linear relationship between noise intensity and annoyance. Noise measurements indicated that the respondents, in general, properly identified the types and magnitudes of noise sources found at their sites.
