Title On the measurement of real-ear attenuation of hearing protectors by standardised test methods.
Bibliographic information NPL Acoustics Report Ac 79, National Physical Laboratory, Teddington, Middlesex, United Kingdom, Feb. 1977. 29p. 27 ref.
Abstract After a review of the development of standards in the USA, United Kingdom and internationally, and a summary of the main provisions of British standard BS 5108, this report describes tests performed according to BS 5108 using 5 types of earmuffs and 1 type of earplugs. The results illustrate the repeatability and typical intersubject variances to be expected. Comparison with results at another laboratory, and with the U.S. procedure are reported.
