Noise Indices for Assessing Domestic Air Conditioner Noise

In the present study, a survey was carried out to examine the capabilities of various noise indices for describing the nuisance caused by exposure to air conditioner noise inside residential apartments. Physical noise measurements were also carried out. 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. The rating level appears not to be a good indicator for such a purpose.
