Sound pressure transformation at the pinna of Mus domesticus.
Sound pressure transformation properties at the pinna of laboratory mice. Mus domesticus, were studied by measuring the sound pressure level of continuous tone at a series of frequencies at the tympanic membrane as a function of the position of a sound source under free-field stimulation conditions. Sound pressure transformation functions showed some prominent spectral notches throughout the fr...
متن کاملWhat ears do for bats: a comparative study of pinna sound pressure transformation in chiroptera.
Using a moveable loudspeaker and an implanted microphone, we studied the sound pressure transformation of the external ears of 47 species of bats from 13 families. We compared pinna gain, directionality of hearing and interaural intensity differences (IID) in echolocating and non-echolocating bats, in species using different echolocation strategies and in species that depend upon prey-generated...
متن کاملPinna movements of the cat during sound localization.
We measured the movements of the external ear, or pinna, using the magnetic search coil technique in cats trained to look at auditory and visual targets for a food reward. No behavioral contingencies were placed on pinna movements. Prominent pinna movements accompany eye movements when the animal orients to either auditory or visual stimuli. In visual trials the pinna movements are coordinated ...
متن کاملSound Source Localization Using a Pinna-based Profile Fitting Method
In a two-microphone approach, interaural differences in time (ITD) and interaural differences in sound intensity (IID) have generally been used for sound source localization. But those cues are not effective for vertical localization in the median plane (direct front). For that purpose, spectral cues based on features of head-related transfer functions (HRTF) have been investigated, but they ar...
متن کاملThe sound-localization ability of cats.
The sound-localization ability of cats To the Editor: The paper by Tollin and colleagues in the March 2005 issue of the Journal of Neurophysiology describes the sound-localization ability of cats trained to orient their eyes to the source of a sound (Tollin et al. 2005). The main finding of this paper, which was the subject of an Editorial Focus (Sparks 2005), was that cats are extremely accura...
