Comparison of admittance measurements before and after removing the effect of the cochlea. (A) The admittance measured in Chinchilla 005 with an open cavity hole measured with an intact cochlea and after the cochlea is drained. (B) Comparisons of mean admittance measurements in normal (intact chain) human ears (Zwislocki 1962 & Rabinowitz 1981) and in the ears of two patients with missing inci (Zwislocki 1962). (C) and (D) Comparisons of admittance measured in individual rabbit and cat ears made with the middle-ear air spaces widely opened, before and after interrupting the ossicular chain (Møller 1965). (E) and (F) Comparisons of admittance measured in individual cat ears with the middle-ear air spaces widely opened, before and after draining the cochlear fluids (Lynch 1981; Puria and Allen 1998).
