• Description:
  A method is developed for measuring the real-ear noise attenuation of insert-type hearing protectors worn in work places. The method involves the use of a circumaural headphone set comprising a muff- type hearing protector fitted with earphone drivers, tested and used to measure noise attenuation for five models of insert-type hearing protectors. Statistical analysis show strong correlations between the attenuation data measured by the field method and standard- method procedures for all nine one-third-octave-band test signals. General recommendations of a measurement procedure are given for the field method. The method is intended primarily as a technique for documenting the variability of hearing protector performance in the work place. [Description provided by NIOSH]
