Effects of Noise on the Physiology and Behavior of Farm-Raised Animals
With the constantly increasing intensity of ambient sound in the modern world, questions arise as to how well the present noise level is tolerated by livestock, and whether noises of still higher intensities and greater frequency will interfere with the efficiency of production. While it has been assumed that most farm animals would seldom be exposed to sounds of extremely high intensities, some animals, nevertheless, are frequently exposed to loud aircraft, truck and motorcycle sounds. Any environmental factor that places farm animals under severe stress can decrease efficiency and profits. One question that needs to be answered is whether sound places livestock under stress and, if it does, the extent and mode of interference, i.e., how does it interfere with production. Although little research has been conducted on the noise problem with farm animals, extensive studies have been made of the responses of man and laboratory animals to various sounds.
