抄録
The application of L_<eq> as a measure of loudness of various noises is investigated. Nine kinds of noise sources, -aircraft noise, super express train noise, train noise, road traffic noise, speech, music, impulsive noise, artificial level-fluctuating noise and steady state noise-are used as stimuli. The duration is about 10 sec except for impulsive noise. Four kind levels are used in each noise source, therefore 36 stimuli are contained in a stimulus series. They are presented in random order and their loudness are judged by magnitude estimation. As a result of experiment, it is found that L_<eq> can be used as a good measure of the loudness of various noises as a first approximation. Strictly speaking, however, there is a slight, but systematical deviation from L_<eq> in PSE's of some noise sources. This fact suggests that it is necessary to add some factors to L_<eq> in order to decide the permissible levels of these noise sources.
