- n. Below mammals, in animals in which the true tympanic is rudimentary or wanting, the quadrate or pedicellate bone, the representative of the malleus; the suspensorium of the lower jaw, or especially its uppermost piece, the hyomandibular or epitympanic: so called by some who suppose it to be the tympanic bone, from the fact that it in part supports the tympanic membrane. See quadrate, n., 3 , hyomandibular, epitympanic, and other compounds of tympanic there cited
- n. In ornithology, sometimes, the tympano-occipital, considered as the true representative in birds of the tympanic of a mammal.

Impedance matching of the tympanic middle ear occurred very early in amniote evolution.
Since the ear is a pressure-gradient ear, the tympanic response at low frequencies is very small, that part of the low frequency sensitivity is extratympanic.
