Many aspects of hearing function are negatively affected by background noise. Listeners,
however, have some ability to adapt to background noise. For instance, the detection of pure …

Response surface methodology was applied to optimize the recovery of ergosterol from an
agroindustrial residue of Agaricus blazei Murrill, by comparing conventional (heat-assisted …

Harmony is an integral part of our auditory environment. Resonances characterised by
harmonic frequency relationships are found throughout the natural world and harmonic …

7. Conclusions Acoustic communication in a frog's natural environment is challenging
because sound is susceptible to distortion during transmission and to masking by chorus …

The cochlear frequency analyzer is a remarkable biological machine, and within the
approximately 30,000 parallel spectral channels of its output in the cochlear nerve temporal …

The ability of 109 single units in the midbrain acoustic centre of frogs (Rana ridibunda, Rana
temporaria) to reproduce 10%, 20 Hz sinusoidal amplitude modulation of a long-duration …

The detection of amplitude modulation (AM) in quiet or in noise improves when the AM
carrier is preceded by noise, an effect that has been attributed to the medial olivocochlear …

Complex sounds, including human speech, contain time-varying signals like frequency
modulation (FM) and amplitude modulation (AM) components. In spite of various attempts to …

In our companion paper, we reported on interaural time difference (ITD)-sensitive neurons
that enhanced, suppressed, or did not change their response when identical AM was added …

Male bullfrogs often amplitude modulate the envelopes of the individual notes (croaks) in
their multinote advertisement calls. These amplitude modulations change the envelope of …
