• Description:
  This report presents a discussion of performance parameters for electronic or active hearing protectors that will meet the needs of underground coal miners. This information is incorporated into a proposed set of specifications that can be used to judge the suitability of a particular electronic hearing protector for the coal mine application. Acoustic and electrical tests were performed on a developmental model of an electronic hearing protector built by the federal Bureau of Mines. A commercially active hearing protector, the British-built acos a-9000/2, was also examined. The recommended test of intelligibility for electronic hearing protectors and other communication systems are used in a coal mine setting is the modified rhyme test (mrt) developed in 1965. The suitability and method of administering this test are discussed. [Description provided by NIOSH]
