Title Laboratory attenuation of earmuffs and earplugs both singly and in combination
Bibliographic information May 1983, Vol.44, No.5, p.321-329. 19 ref.
Abstract The incremental performance to be gained by double ear protection was investigated by measuring real-ear attenuation in 10 subjects wearing, singly or in combination, several types of earplugs and earmuffs. In all cases, the combination plugs + muffs outperformed either device individually, except at 1kHz for one combination. At ≥2kHz all plug + muff combinations provided attenuation approximately equal to the bone-conduction limits of the skull. Below 2kHz, the type of earplug chosen influenced the total attenuation regardless of the type of earmuff used.
