Abstract:
Temperature-dependent spontaneous otoacoustic emissions (SOAEs) are reported for the first time in Rana catesbiana, the American bullfrog. A low-noise acoustic measurement system was developed for recording SOAEs in a readily available species of frog. SOAEs were detected in one of five anesthetized frogs during late autumn. The frequency of the emission was temperature dependent, increasing from 1612–1762 Hz, with a change in body temperature from 22.1°–25.3°C. The SOAE level ranged from −3 to +4 dB SPL and was uncorrelated with temperature over the range studied. SOAEs have been reported in Rana esculenta [A. R. Palmer and J. P. Wilson, J. Physiol. 324, 66P (1981)] and Rana temporaria [Wilson et al., in Auditory Frequency Selectivity, edited by B. C. J. Moore and R. D. Patterson (Plenum, New York, 1986), pp. 39–46] . The emissions in these other species are also temperature dependent [P. van Dijk and H. P. Wit, J. Acoust. Soc. Am. 82, 2147–2150 (1987)]. Experiments are recommended to explore the possibility that the presence and incidence of SOAEs are seasonally dependent in this species. [Work supported in part by NIH.]
