PROCEEDINGS of the HUMAN FACTORS SOCIETY 36th ANNUAL MEETING-1992 TECHNOLOGY ADVANCEMENTS IN HEARING PROTECTION: AND UNIFORM ATTENUATION ACTIVE NOISE REDUCTION, FREQUENCY/AMPLITUDE-SENSITIVITY,

Conventional hearing protection devices have often been implicated in compromised auditory perception, degraded signal detection, and reduced speech communication abilities. Recent technological developments have been used to augment hearing protectors in an attempt to alleviate these problems for the user, while at the same time providing adequate attenuation. Operational characteristics, design features, performance data, and applications for active noise reduction, sound transmission, frequency-selective, adjustable attenuation, amplitude-sensitive, and uniform attenuation devices are discussed
