Title The effects of hearing protectors on auditory localization: Evidence from audio-visual target acquisition
Bibliographic information 2000, Vol.6, No.3, p.309-319. Illus. 14 ref.
Abstract Response times (RT) in an audio-visual target acquisition task were collected from three participants while wearing either circumaural earmuffs, foam earplugs, or no hearing protection at all. Analyses revealed that participants took significantly longer to locate and identify an audio-visual target in both hearing protector conditions than they did in the unoccluded condition, suggesting a disturbance of the clues used by listeners to localize sounds in space. RTs were significantly faster in both hearing protector conditions than in a non-audio control condition, indicating that auditory localization was not completely disrupted. Results are discussed in terms of safety issues involved with wearing hearing protectors in an occupational environment.
