Hearing abilities of your unusual pet
Do reptiles hear well? Can your pet listen to absolute radio with you?
The organ of hearing of reptiles in the pattern is close to the organ of hearing of frogs. It consists of a middle ear with a tympanic membrane and one auditory ossicle - a stapes, transmitting vibrations of the membrane to a round window that separates the cavity of the inner ear. This mechanism enhances the sounds propagating in the air. In the inner ear, the cochlea (lagena) is isolated, which serves as an apparatus for analyzing and encoding acoustic signals. The cochlea is not yet complex, and in most species it is a bag-shaped outgrowth. This corresponds to the relatively small role of hearing in the life of reptiles. They perceive sounds in the range of 20-6000 hertz (Hz), but most hear well only in the range of 60-200 Hz. Crocodiles better perceive sounds with a frequency of 100-3000 Hz. For snakes, hearing is especially weak; they are devoid of a tympanic membrane and perceive mainly sounds propagating along a substrate (earth) or in water (the so-called seismic hearing). The same is true of serpentine lizards. Sound transmission from the substrate to the oval window of the middle ear is provided by square and square-zygomatic bones.
The relatively limited hearing of snakes corresponds to their weak voice capabilities. The auditory abilities of turtles are also low, the eardrum of which is thick, and the auditory meatus in some species is closed by thickened skin.
Most reptiles are dumb; their sound world is poor. The sounds of snakes (hissing, wheezing, rattling of tail rattles) and some lizards (creaking scales) often serve as a menacing warning. So the sound of the radio, maybe, will reach your snake, but it will obviously not perceive it.
