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....

Actieve geluidsreductie (ANR) is, mits goed toegepast, een waardevolle aanvulling op passieve gehoorbescherming.

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...
