Threshold of hearing and signal bandwidth necessary for horizontal sound localization

Abstract (in Japanese) (See Japanese page) 
(in English) This paper clarifies the relationship between subjects hearing threshold level and signal bandwidth necessary for horizontal sound localization. Ten subjects listened to white noise, low-pass (0.5, 1, 2, 4, 8 kHz) or high-pass (2, 4, 8, 12, 16 kHz) filtered noise stimuli. Localization accuracies as a function of filter cut off frequency are similar among subjects. Those for low-pass filtered noises, however, show important individual difference. Almost subjects can hardly localize heavily low-pass (0.5, 1, 2 kHz) or high-pass (12, 16 kHz) filtered noises. For subjects who have severe hearing losses at higher frequency, the narrower the stimulus bandwidth the less the localization accuracy.
