This process lessens movements of the auditory ossicles and thus dampens vibrations caused by loud sounds to protect structures of the internal ear. These two muscles are the tensor tympani (Eustachian) muscle and …
WebThe hearing range of the cod Gadus morhua is about 2 to 500 Hz, with peak sensitivity near 20 Hz - probably typical for most bony fish species that lack the adaptations described below. In some bony fish species, the swim bladder is associated with adaptations for enhanced sound reception at higher frequencies.
