Abstract
A survey was carried out in the present study to determine the noise indices which are capable of describing the nuisance caused by exposure to air-conditioner noise inside residential apartments. This survey consisted of a questionnaire, which asked the respondents to rate their feelings of annoyance and loudness on the air-conditioner noise and to give their preference of a change in the noise levels. Physical noise measurements were also carried out. A total of 57 noise spectra and 399 respondents were involved in the survey. Results show that the Zwicker's loudness level and the percentile level of 90% exceedence are the two major indices for air-conditioner noise assessment. Tonality appears not to be a good indicator for such a purpose.
