.../ Summary: In grasshoppers, the localization of sounds with ambiguous or conflicting directional cues depends on the magnitude and temporal position of each cue. This gives insight into general principles of directional hearing. Directional hearing Orthopteran Acoustic communication Precedence...

... Directional hearing Crickets Katydids Many animals communicate acoustically in large and noisy groups (choruses), where the detection, identification and discrimination of sound signals is a common problem. In humans, considerable research over the last several decades has been devoted...

... mechanical response of the antennae under different stimulus intensities and frequencies requires further investigation, as does the analysis of phase, which may provide further information on the steady state and dynamic mechanisms of directional hearing in Drosophila . As the aristae seem to have evolved...

... was maintained for a wide range of signal-to-noise ratios because of the more sharply tuned sensory system and selective attention mechanisms. Finally, the rainforest cricket also showed an almost perfect match between the filter for sensitivity and the peripheral filter for directional hearing, in contrast...

...Brandon M. Casper; David A. Mann SUMMARY Auditory evoked potentials (AEPs) were used to measure the directional hearing thresholds of the white-spotted bamboo shark Chiloscyllium plagiosum and the brown-banded bamboo shark Chiloscyllium punctatum at four frequencies and seven directions, using...

... hearing is mediated by intertympanal mechanical coupling, a process that amplifies small acoustic cues into significant interaural time and amplitude differences ( Miles et al., 1995 ; Robert et al., 1996 ; Robert and Hoy, 1998 ). acoustics directional hearing orientation Diptera parasite...

... of the pinna in directional hearing has often been ignored by the use of closed field sound delivery ( Erulkar, 1972 ). A notable exception has been in the study of hearing in bats, where the pinnae often exceed the dimensions of the head and have been clearly implicated in directional hearing ( Grinnell, 1963...
