Abstract (in Japanese) (See Japanese page) 
(in English) Under the very loud noise in a running train, it is difficult to listen to broadcasts. An increase in the broadcasting sound level is a possible solution to this problem. However, excessively increasing the broadcasting sound level is unpleasant for passengers. To solve this problem, optimum control of the sound level is required. In this study, the optimum broadcasting sound levels for various noise levels are investigated by performing subjective listening tests using real train announcements and recorded train noise. However, it was found that the optimum broadcasting sound level strongly depends on 1) the noise spectrum and 2) the variation among announcements. To solve the problem, we propose 1) a new alternative noise evaluation method to the conventional A-weighted method and 2) a method that reduces the stimulativeness of phonemes. Using these methods, optimum broadcasting sound level control that is less dependent on the noise spectrum and variation among announcements can be realized.
