“…The proposed mechanism resembles the swimbladder-inner ear coupling in otophysine fish, where coupling of the air-filled swimbladder to the inner ear by the Weberian ossicles enhances sound sensitivity by 40 dB or more [25]. The turtle ear also closely resembles the ear of the clawed frog (Xenopus laevis), which has a cartilaginous tympanic disc and an air-filled middle ear cavity that adapt the ear for underwater hearing [23,26 -28].…”

“…We characterized the acoustic impedance (ratio of sound pressure to particle velocity) of our experimental tank conditions as suggested by Popper and Fay (2011), using the calibration measurements at different three SPLs: 118, 130, and 145 dB (re. : 1 µPa).…”

“…Thus, in the current study we characterized the midshipman auditory thresholds in terms of both sound pressure and particle motion. As suggested by Popper and Fay (2011), we also report the impedance (ratio of pressure to particle velocity) of our test tank (see Fig. 1a) so that the acoustic impedance of the tank conditions in this study can be used in comparison with that of future fish hearing studies.…”

“…In this study, we used stimulus frequencies in a lower range from 20 to 200 Hz because the zebrafish embryos/larvae that we recorded from were likely more sensitive to lower frequencies due to the fact that they had not yet developed the Weberian ossicles, an auditory accessory known to increase auditory sensitivity at high frequencies. The saccule and utricle of zebrafish of one week old or younger are only "motion sensitive" via a direct stimulus pathway as described by Popper and Fay (2011), and the inner ear of zebrafish is not yet pressure sensitive until the initial formation of the Weberian ossicles at about 20 dpf (Grande and Young 2004). The stimulus probe we used is thought to provide acoustic particle motion via direct inertial stimulation to hair cells in the otocyst.…”
