Title Occupational Hearing Loss from Non-Gaussian Noise
520 3# - SUMMARY, ETC.
Summary, etc Noise levels are truly continuous in relatively few occupations,<br/>with some degree of intermittency the mostcommoncondition. Thesound<br/>levels of intermittent noise are often referred to as non-Gaussian in that<br/>they are not normally distributed in the time domain. In some conditions,<br/>intermittent noise affects the ear differently from continuous noise, and it is<br/>this assumption that underlies the selection of the 5-dB exchange rate<br/>(ER). The scientific and professional communities have debated this<br/>assumption over recent decades. This monograph explores the effect of<br/>non-Gaussian noise on the auditory system. It begins by summarizing an<br/>earlier report by the same author concentrating on the subject of the ER.<br/>The conclusions of the earlier report supported themore conservative 3-dB<br/>ER with possible adjustments to the permissible exposure limit for certain<br/>working conditions. The current document has expanded on the earlier<br/>report in light of the relevant research accomplished in the intervening<br/>decades. Although some of the animal research has supported the<br/>mitigating effect of intermittency, a closer look at many of these studies<br/>reveals certain weaknesses, along with the fact that these noise exposures<br/>were not usually representative of the conditions under which people<br/>actually work. The more recent animal research on complex noise shows<br/>that intermittencies do not protect the cochlea and that many of the<br/>previous assumptions about the ameliorative effect of intermittencies are no<br/>longer valid, lending further support to the 3-dB ER. The neurologic<br/>effects of noise on hearing have gained increasing attention in recent years<br/>because of improvements in microscopy and immunostaining techniques.<br/>Animal experiments showing damage to auditory synapses from noise<br/>exposures previously considered harmless may signify the need for a more<br/>conservative approach to the assessment of noise-induced hearing loss and<br/>consequently the practice of hearing conservation programs.
