Standardised hearing protector measurements

  • Poulsen, Torben (Project Manager)

    Project Details


    Standards and test methods in relation to sound attenuation of hearing protectors are evaluated. The sound field requirements in ISO 4869-1 are erroneous and misleading and possible new formulations of the requirements are under development. Comparisons are made of measurements carried out according to ISO and ANSI methods.
    T. Poulsen serve as chairman for the ISO working group responsible for standardized hearing protector test methods.
