Sound localization and occupational noise
OBJECTIVE The aim of this study was to determine the effects of occupational noise on sound localization in different spatial planes and frequencies among normal hearing firefighters. METHOD A total of 29 adults with pure-tone hearing thresholds below 25 dB took part in the study. The participants were divided into a group of 19 firefighters exposed to occupational noise and a control group o...
متن کاملSound localization in noise and sensitivity to spectral shape
Individual differences exist in sound localization performance even for normal-hearing listeners. Some of these differences might be related to acoustical differences in localization cues carried by the head related transfer functions (HRTF). Recent data suggest that individual differences in sound localization performance could also have a perceptual origin. The localization of an auditory tar...
متن کاملRobust low-resource sound localization in correlated noise
In this paper we address the problem of sound source location using the time difference of arrival (TDOA) technique in an environment containing stationary correlated noise. We present a robust low-complexity method for enhancing estimation of sound direction, augmenting the well-known Generalized Cross-Correlation with Phase Transform (GCCPHAT) approach. In the proposed method, the estimated c...
متن کاملAuditory efferents facilitate sound localization in noise in humans.
The mammalian auditory system contains descending neural pathways, some of which project onto the cochlea via the medial olivocochlear (MOC) system. The function of this efferent auditory system is not entirely clear. Behavioral studies in animals with olivocochlear (OC) lesions suggest that the MOC serves to facilitate sound localization in noise. In the current work, noise-induced OC activity...
متن کاملMeasuring Sound and Noise
The European Community Green Paper on Future Noise Policy (1996) recognised that environmental noise is “one of the main local environmental problems in Europe” but that it has had a lower priority than other environmental problems, such as air or water pollution. It also recognised that, despite significant reductions in the noise produced by individual sources, total exposure to environmental...
