By Arthur N. Popper, Anthony Hawkins

The assembly of Aquatic Noise 2013 will introduce contributors to the latest examine facts, regulatory concerns and wondering results of synthetic noise and should foster serious cross-disciplinary dialogue among the contributors. Emphasis could be at the cross-fertilization of rules and findings throughout species and noise resources. As with its predecessor, the consequences of Noise on Aquatic lifestyles: third overseas convention will motivate dialogue of the impression of underwater sound, its rules and mitigation of its results. With over a hundred contributions from best researchers, a variety of resources of underwater sound should be thought of.

1987). Because these sensory cells and neurons never regenerate, at least in the mammalian inner ear, the hearing deficits that this degeneration causes are permanent and progressive with increasing exposure time. Over the last 40 years, many groups have attempted to describe the functionally important structural changes underlying noise-induced hearing loss (NIHL) in animal models. The classic functional measure of NIHL is the auditory threshold. , a measure of the lowest sound pressure level required at each test frequency to elicit an auditory percept.

C. Liberman impossible to quantify based on an audiogram, a number of laboratories are pursuing the idea that hearing in noise or performance on other complex auditory tasks may be a useful measure of noise-induced neuropathy. The most sobering aspect of the work on noise-induced neuropathy is its implications for damage risk criteria. All damage risk criteria are constructed assuming that the audiogram is the gold standard functional test and therefore that an exposure that causes only a temporary threshold shift is essentially benign (National Institute for Occupational Safety and Health 1998).
