• Description:
  Hearing protector attenuation data have been demonstrated to exhibit bimodal characteristics due to poorly fitting protectors. The data have been modeled with two distributions [Murphy and Franks, J. Acoust. Soc. Am. 106, 2262 (1999)]. The bimodal distribution model was used as the basis of a statistical classifier for an individual's attenuation data to identify whether or not the data come from a poor or well fit distribution. Training classes were developed from ANSI S12.6 Method B subject fit data [Franks et al., Ear Hear. 21, 218-226 (2000)] for the EAR Classic (n=25), EAR Express (n=20) and Howard Leight MAX (n=25) earplugs. Real ear attenuation at threshold was measured under circumaural headphones for each earplug with a panel of 20 subjects. Preliminary results suggest that data from 500 or 1000 Hz yield the best ability to separate the attenuations. [Description provided by NIOSH]
