Rodent hearing: apparatus for behavioral measurements with ultrasounds.
For frequencies from 4 to 80 kHz, the acoustic reliability, behavioral reliability and overall performance of an open platform were entirely satisfactory in measurements of "absolute" auditory thresholds (using a reward operant procedure) in Rattus norvegicus. Equal satisfaction was provided by a rodent-holder in measurements of Preyer reflex thresholds over a similar frequency range in R. norvegicus, Mus musculus, Clethrionomys glareolus, Meriones unguiculatus and Sigmodon hispidus.
