Frogs rely heavily on acoustic communication to mediate their social interactions in reproduction. The frequency tuning of their ears tends to match that of the calls promoting effective communication. In small species such as the túngara frog, extratympanic pathways involving the body wall and lungs can also be relevant routes of sound reception. Electrophysiological recordings from the midbrain of the túngara frog indicate the greatest auditory sensitivity around 1-1.1 kHz and elevated around 2 kHz. This tuning is a close match to the peaks in their calls (around 1000 Hz for whine and 2400 Hz for chuck) and reaches surprisingly low frequencies considering their small body size, raising the question of how is the low peak received by the auditory system. We characterized the tuning of the eardrums and body walls using Doppler laser vibrometry while stimulating anesthetized subjects with a series of pure tones ranging from 0.2 to 18 kHz and having an amplitude of 80 dB at the subject. Each data set was collected in 5 repetitions with the auditory stimulus and 5 repetitions without the auditory stimulus as a control. The eardrum was expected to be the main auditory pathway and the body wall was a secondary but relevant pathway potentially tunned to lower frequencies. Both the eardrum and the body wall showed significant vibration response to the stimuli with the highest sensitivity at 2-3 kHz. This matches the auditory tuning of other small frogs but it is mismatched with the electrophysiological peaks at low frequencies recorded in previous studies. Our results indicate that either there is a significant loss (~ 50 dB) of the mating call's energy in the tungara frog's auditory system or that the low frequencies (< 1.5 kHz) are received through an undescribed mechanism.
