Introduction: Elevated hearing thresholds have been documented in some astronauts after long-term spaceflights although noise levels were lower than those normally associated with noise-induced hearing loss in ground-based operations. The present study was conducted to determine whether prolonged exposure (70 h) to levels (72 dBA) recorded on...

Active noise reduction is a successful addition to passive ear-defenders for improvement of the sound attenuation at low frequencies. Design and assessment methods are discussed, focused on subjective and objective attenuation measurements, stability, and high noise level applications. Active noise reduction systems are suitable for integration...

In an earlier study we derived robust frequency-weighting functions for prediction of the intelligibility of short nonsense words.These frequency-weighting functions are applied for prediction of intelligibility such as with the speech transmission index (STI).Six independent experiments revealed essentially similar frequency-weighting functions...

The revised model for the speech transmission index (STIr, Speech Communication 28 (1999) 109), was validated with an independent set of 68 test conditions. For a subset of 18 conditions, including only additive noise and band-pass limiting, it was veri.ed that the STIr provides a good prediction of the CVC-word score. The additional...
