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...

While the Speech Transmission Index ~STI! is widely applied for prediction of speech intelligibility in room acoustics and telecommunication engineering, it is unclear how to interpret STI values when non-native talkers or listeners are involved. Based on subjectively measured psychometric functions for sentence intelligibility in noise, for...

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...

When listening to languages learned at a later age, speech intelligibility is generally lower than when listening to one's native language. The main purpose of this study is to quantify speech intelligibility in noise for specific populations of non-native listeners, only broadly addressing the underlying perceptual and linguistic processing. An...

To deal with the effects of nonnative speech communication on speech intelligibility, one must know the magnitude of these effects. To measure this magnitude, suitable test methods must be available. Many of the methods used in cross-language speech communication research are not very suitable for this, since these methods are designed to...

Purpose: The NATO Ad-Hoc Working Group on Narrow Band Voice Coding (AHWG-NBVC) was tasked to select a new standard 1200 and 2400 bps vocoder for use throughout NATO. For this purpose, the AHWG has initiated a selection process, that is aimed at evaluating which of three candidates is the most suitable coder. ---- Method: During the first of...

A laboratory model of the wireless "Communications EarPlug" (w-CEP) was developed. Standard communication earplugs (using wires) are known to offer relatively good intelligibility of intercom speech at high ambient noise levels. The intercom sound is produced by means of a commercially available miniature transducer, integrated in the earplug....

The speech intelligibility and quality of a MELP low bitrate speech coder (1200 bps) were investigated in an experiment, in which the speech coder was either combined with or without a noise pre-processing system. The central question to be addressed was to what extent the performance of the speech coder could be improved by adding a noise pre...

Current objective measures for predicting the intelligibility of speech by an index assume that this can be obtained by simple addition of the contributions of individual frequency bands. The Articulation Index (AI, and the related Speech Intelligibility Index), and the Speech Transmission Index (STI) are based on this assumption. There is...

De spraakverstaanbaarheid van het omroepsysteem in de Wijkertunnel wordt bepaald door de eigenschappen van het omroepsysteem, de akoestische eigenschappen van de tunnel en de in de tunnel aanw ezige lawaaibronnen. Het lawaai dat door de aanwezige stuwventilatoren wordt geproduceerd blijkt tot een belangrijke reductie van de...

In een luisterexperiment zijn de prestaties vergeleken van automatische spraakherkennigssystemen (ash) en luisteraars. Luisteraars scoorden (uiteraard) beter, maar lieten zich meer beinvloeden door zinslengte ASH-systemen meer door perplexiteit.
