Abstract

This paper presents a methodology and related experimental results as a first attempt to answer the question of anuran audition and their ability to localize sound at acoustic frequencies they should not. An achiral digital holographic interferometer is designed so as to simultaneously measure the left and right tympanic vibrations on living specimen. The tympanic membranes are excited by an acoustic antenna including 22 loudspeakers emitting sound in the frequency range 1000 Hz to 3000 Hz. The first experimental results are presented.
