520 | $aThe Real Ear Attenuation at Threshold (REAT) of ear foam earplugs was determined, using three methods of presentation of the test tones during a single fitting of the earplug. The three presentation methods were (a) sound-field listening; (b) TDH49 earphone mounted in the shell of a circumaural earmuff; and (c) TDH49 earphone in a model 51 cushion. Threshold were tested once under each condition | ||
