... background noise levels of the birds' cliffside nesting habitats. Yet the most sensitive thresholds (measured in a very quiet, semi-anechoic chamber) were below these ambient noise conditions. This suggests that at times, the natural soundscape of the cliffside habitat would mask these animals' hearing...

... and locating prey and predators. Many terrestrial animals increase the amplitude of their acoustic signals to partially compensate for the masking effect of noise (the Lombard response), but it has been suggested that cetaceans almost fully compensate with amplitude adjustments for increasing noise levels...

...). Consequently, lower amplitude responses in the murre seemed to be masked by neurophysiological noise. This noise (or the lower detectable responses) may have stemmed from multiple sources (location of electrodes, grounding, animal movement, muscular activity etc.) and time was limited, as was sample size (we...

We propose that regulation of motor activity by photic stimuli in zebrafish larvae serves a behavioral goal of maximizing exposure to well lit environments...

Data show that the carp's hearing is only moderately masked by the quiet habitat noise level of standing waters (mean threshold shift 9 dB) but is heavily...
