Abstract: Based on two questionnaire surveys conducted in Beijing, the data about the community response to the public noise are obtained. Objective noise data are also measured by a sound level meter. Three curves, which show the relationship between annoyance and equivalent A-weighted sound level, perceived noisiness and perceived noise level, are also established. As the survey results indicated, the public noise is generally considered "noisy", and makes citizens feel somewhat annoyed. Most people are apt to take negative measure to deal with the disturbing public noise, although some people can take effective ways to treat it. Furthermore, non-acoustic factors affect the annoyance evaluation of public noise significantly. The research also indicates that the perceived noisiness and perceived noise level could be taken as indicators for evaluating annoyance of public noise.
