Title The usefulness of various types of individual hearing protectors for sailors
Bibliographic information 1981, Vol.32, No.3/4, p.213-223. Illus. 12 ref.
Abstract Report of a study to assess the noise reduction efficiency of 10 types of hearing protectors by measuring temporary threshold shift in wearers and by means of a questionnaire; the efficiency was also assessed in relation to the noise spectra encountered in the engine rooms of 4 types of ship. Sailors exposed to noise without hearing protectors had 13-15dB temporary threshold shift in the higher frequencies, whereas the shift was only 5-8dB in those wearing various types of hearing protector. Subjective evaluation of hearing protectors showed a clear preference for imported models.
