Surprisingly little is known about their hearing, despite their imperiled status. Understanding sound sensitivity is vital when we seek to manage the impacts of man-made...

However, the vulnerability of pilot whales to anthropogenic noise is still of concern as the ability to cope with increasing background noise may be limited. Our study shows that combining propagation...

Bats tackle these problems by deploying a remarkable array of auditory behaviors, sometimes in combination with the use of other senses. Behavioral...

Marshall; Henrik Brumm ABSTRACT Animals that use vocal signals to communicate often compensate for interference and masking from background noise by raising the amplitude of their vocalisations. This response has been...

Results indicate that ringed seals possess hearing abilities comparable to those of spotted seals ( Phoca largha ) and harbor seals ( Phoca vitulina ), and considerably better than previously reported for ringed and harp seals.

Specifically, a number of studies have suggested that vocal plasticity at the emitter's level allows birds to counteract...

This detailed examination of hearing abilities in wild Bristol Bay belugas provides a basis for a better understanding of the potential impact of anthropogenic noise on a noise-sensitive species. Such information may help design noise-limiting mitigation measures that could be applied to areas heavily...

Thresholds were measured by recording rhythmic evoked potentials (the envelope following response) to a test series of short (eight cycles) tone pips with a pip rate of 1000 s −1 . TTS increased...

First, we examined the effect of noise sound pressure level (SPL; 130,140, 160 or 170 dB re 1 μPa) on goldfish hearing thresholds after 24 h of noise exposure. Second, in a long-term experiment using 170 dB re 1 μPa...

We examined the short- and long-term effects of increased ambient sound on the stress and hearing of goldfish ( Carassius auratus ; a hearing specialist). We reared fish under either quiet(110-125 dB re 1 μPa) or noisy...
