Young People: Taking Few Precautions Against Hearing Loss in Discotheques

This study evaluated adolescents' music-listening risk and protective behaviors in discotheques. While frequently standing close to the loudspeakers, taking few breaks, and hardly using hearing-protection devices, many are at risk of developing permanent hearing loss. Assessing visiting mode may be a first and quick screener to identify...

Digitally controlled active noise reduction with integrated speech communication

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...

Actieve geluidsonderdrukking in gehoorbeschermers

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

Balancing speech intelligibility versus sound exposure in selection of personal hearing protection equipment for Chinook aircrews

Background: Aircrews are often exposed to high ambient sound levels, especially in military aviation. Since long-term exposure to such noise may cause hearing damage, selection of adequate hearing protective devices is crucial. Such devices also affect speech intelligibility. When speech intelligibility and hearing protection lead to conflicting...

Development of the wireless "Communications EarPlug" for application in military aviation

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....
