| Abstract |
Studies are described showing the speech intelligibility obtained by persons while wearing conventional or electronic hearing protectors under various conditions (various speech and noise levels and spectra, with and without conventional hearing protectors, different hearing sensitivities). A computer model was generated to simulate an individual undergoing speech intelligibility tests. For speakers talking at normal voice levels at noise levels of 65dB or less, it was found that conventional hearing protectors significantly reduced speech intelligibility. Under the same conditions, electronic protectors provided scores equal to those for the unprotected individuals while providing protection from high noise levels. The conclusion is drawn that electronic hearing protection is valuable in areas where high noise level is intermittent. |
