... by The Company of Biologists Ltd 2023 Summary: Hearing abilities differ between shark species, mainly with respect to bandwidth rather than sensitivity, with benthopelagic sharks exploiting higher frequencies than bottom-dwelling sharks. Elasmobranchs Hearing sensitivity Electrophysiology New...

...Tanya B. Lauridsen; Christian Brandt; Jakob Christensen-Dalsgaard ABSTRACT Hearing sensitivity has been extensively investigated, often by measuring the auditory brainstem response (ABR). ABR measurements are relatively non-invasive, easy to reproduce, and allow the assessment of sensitivity when...

... of three Fukomys species reveal a highly restricted hearing range. Hearing sensitivity Subterranean mammals Sound localization Auditory fovea Inner ear Middle ear African mole-rats of the genus Fukomys spend their entire life in underground tunnel systems. The aphotic subterranean...

... is a function of hearing threshold versus stimulus carrier frequency, presented a U-shape with a region of high hearing sensitivity (within 20 dB of the lowest threshold) between approximately 20 and 120 kHz. At frequencies lower than this high-sensitivity region, thresholds increased at a rate of approximately...

.... Data on the hearing ability of these fish are, however, needed to show that they have the sensory ability to detect the frequencies in their sounds. The present study determines the hearing sensitivity in three different anemonefish species ( Amphiprion frenatus,Amphiprion ocellaris and Amphiprion...
