Sound attenuation achieved with several routinely procured standard Air Force devices was determined with 10 subjects. Devices and their combinations studied were earplugs, earmuffs, earplugs and earmuffs, communication-type headset-microphone, and headset-microphone with dry cotton in the ear canals. Results indicate that occasionally a need may exist to measure the protection an individual is getting with ear-protective devices. Also, results with the earmuffs were somewhat different from results found at another facility. Attenuation resulting from dry cotton and a headset-microphone in combination suggests the need to investigate speech intelligibility with that condition. Author
