Abstract:

The application of exposure effect relationships to transform a SLM to a noise annoyance meter is described. An annoyance scale using the most frequently used category descriptors related to noise for community noise assessment in Japan was developed. These descriptors were elicited from a listening experiment where the subjects listened to various kinds of noise sources for five minutes in or near their houses in and around Nagano city. As the equivalent continuous A-weighted sound pressure level (L_Aeq,(5min) [dB]) was measured for each of the sounds, it became possible to link the noise level to the annoyance descriptor. Thereby an experimental noise annoyance meter which can evaluate psychological effects on humans at the same time as L_Aeq,(5min) was developed. After having constructed the annoyance meter, it was validated using a separate sample of residents from other typical cities in Japan. They were presented to similar noise stimuli and both the measured noise levels and associated annoyance descriptors associated with the sounds. Through this process, the annoyance meter was shown to have face validity. It is therefore proposed that the noise annoyance meter could be applied for combined noise exposure and noise impact rating in Japan.
