title = "Noise evaluation based on loudness-perception characteristics of older adults",
abstract = "The frequency-weighting A used for noise measurement was determined based on hearing characteristics expressed as equal-loudness-level contours. The time-averaged, A-weighted sound level (LAeq) of a sound corresponds well with the perceived loudness. However, good correspondence between LAeq and the perceived loudness is confined to cases in which listeners are young people with normal hearing. This study used a psychoacoustic experiment to investigate loudness of various sounds perceived by older people aged over 60. Analyses of results revealed that sound levels weighted by listeners' hearing characteristics matched the judged loudness better than LAeq values did. This report describes the development of a noise evaluation method that can evaluate noises for senior citizens more accurately than the conventional method using A-weighting.",
