Title Comparative study of protective power of earmuffs of Polish and foreign manufacture
Original title Porˇwnanie własności ochronnych krajowych i zagranicznych nausznikow prezeciwhałasowych [in Polish]
Bibliographic information 1980, Vol.30, No.104. p.63-74. Illus. 6 ref.
Abstract 20 models from Poland, Finland, England, USA, USSR, Australia, Hungary, and West Germany were tested. Acoustic efficiency and attenuation power were measured. A rapid method of calculating the attenuation power using a sum of imaginary spectra and a mini-computer is presented. There was a relation between the shape of the attenuation curve and the acoustic efficiency.
