Furuyama, Takafumi; Hase, Kazuma; Hiryu, Shizuko; Kobayasi, Kohta I. (2018). Hearing sensitivity evaluated by the auditory brainstem response in Miniopterus fuliginosus. The Journal of the Acoustical Society of America, 144(5): EL436 - EL440.
This study evaluated the hearing sensitivity of Miniopterus fuliginosus, a frequency-modulating (FM) bat species, by measuring the auditory brainstem responses in the inferior colliculus. The average audiogram was U-shaped. The mean threshold decreased gradually as the frequency increased from 16 to 40 kHz and then decreased rapidly as the frequency reached 46 kHz, with the peak sensitivity occurring at the terminal portion of the echolocation pulse between frequencies of 44 and 56 kHz. The shape of audiogram of M. fuliginosus is consistent with other FM bats, and is compared with its vocalization behavior.
