Description: Fundamental laws of sound propagation and for the determination of sound pressure are reviewed. Typical characteristics of two individual hearing protection devices (ear plugs and ear muffs) are presented. These devices generally offer a maximum level of protec tion for sounds having a frequency greater than 2000 Hz.Two practical examples are used in order to demonstrate a method for determining the level of protection associated with these devices for sounds for which the spectral distribution of noise intensity is known. It is recom mended that such measurements of noise levels be conducted for most of the agricultural machines, machine combinations, and other noisy equipmentused on Canadian farms, and also on the acoustical charac teristics of the various individual hearing protection devices available on the market, in order to select the most appropriate protection device for each case. Farmers and agricultural workers should be informed of the results of such studies so that they can adopt and use the recom mended protection devices.
