Title Method for determining the necessary mechanical characteristics of ear protectors for use in specific acoustic conditions, using the example of a ship's engine room
Original title Metoda wyznaczania wymaganych wartości parametrów techniczno-konstrukcyjnych nauszników przeciwhałasowych przeznaczonych do stosowania w określonych warunkach akustycznych na przykładzie maszynowni statków [in Polish]

Abstract Description of a method used to determine the mechanical characteristics required of ear protectors in relation to the acoustic environment in which they are to be used. The nomograms and regression equations presented are based on experimental data from the study of correlations between certain parameters (mass, volume, pressure on or adhesion to the wearers' head) in 21 models of ear protectors from different sources and their acoustic effectiveness. The regression factors make it possible to determine the characteristics likely to ensure the acoustic effectivneness required for a given acoustic environment. Details are given of the design of ear protectors for use in the engine rooms of sea-going vessels.
