Effects of underwater noise on auditory sensitivity of a cyprinid fish. Hear

The underwater acoustic environment is inherently loud as a result of ambient sounds and an increasing amount of noise from anthropogenic sources. The report summarizes two sets of experiments which examined how white noise and boat engine noise impact auditory physiology of the fathead minnow (Pimephales promelas), a freshwater fish that is widely distributed in the North America. The results show that threshold elevation and recovery after noise exposure are frequency and exposure duration dependent. 2
