Acoustic communication signals are inevitably challenged by ambient noise. In response to
noise, many animals adjust their calls to maintain signal detectability. However, the …

Although acoustic communication is inevitably influenced by noise, behaviorally relevant
sounds are perceived reliably. The noise-tolerant and-invariant responses of auditory …

In the cochlea of the mustached bat, cochlear resonance produces extremely sharp
frequency tuning to the dominant frequency of the echolocation calls, around 61 kHz. Such …

Electrophysiological studies on duration-tuned neurons (DTNs) from the mammalian
auditory midbrain have typically evoked spiking responses from these cells using monaural …

In constant frequency–frequency modulation (CF–FM) bats, the CF–FM echolocation signals
include both CF and FM components, yet the role of such complex acoustic signals in …

The environment noise may disturb animal behavior and echolocation via three potential
mechanisms: acoustic masking, reduced attention and noise avoidance. Compared with the …

In nature, communication sounds among animal species including humans are typical
complex sounds that occur in sequence and vary with time in several parameters including …

Descending circuitry can modulate auditory processing, biasing sensitivity to particular
stimulus parameters and locations. Using awake in vivo single unit recordings, this study …

Background Most species of bat making echolocation use Doppler-shifted frequency of
ultrasonic echo pulse to measure the velocity of target [1]. To perform the fine-frequency …
