Résumé : |
To determine safe output sound pressure levels (SPL) for sound amplification devices to preserve hearing sensitivity after usage. Design: A mathematical model consisting of the Modified Power Law (MPL) (Humes & Jesteadt, 1991 Humes, L.E. & Jesteadt, W. 1991. Modeling the interactions between noise exposure and other variables. J Acoust Soc Am, 90, 182188.[Crossref], [PubMed], [Web of Science ®], [Google Scholar]) combined with equations for predicting temporary threshold shift (TTS) and subsequent permanent threshold shift (PTS) (Macrae, 1994b Macrae, J.H. 1994b. Prediction of asymptotic threshold shift caused by hearing aid use. J Speech Hear Res, 37, 14501458.[Crossref], [PubMed], [Google Scholar]) was used to determine safe output SPL. Study sample: The study involves no new human subject measurements of loudness tolerance or threshold shifts. PTS was determined by the MPL model for 234 audiograms and the SPL output recommended by four different validated prescription recommendations for hearing aids. Results: PTS can, on rare occasion, occur as a result of SPL delivered by hearing aids at modern day prescription recommendations. The trading relationship of safe output SPL, decibel hearing level (dB HL) threshold, and PTS was captured with algebraic expressions. Better hearing thresholds lowered the safe output SPL and higher thresholds raised the safe output SPL. |
