Hypotheses
Linear relationship between TEOAEs and the PTA_2 kHz (Collet et al, 1991).
Strong discriminant efficiency of the 2 kHz octave frequency (Smoorenburg, 1992).
The mechanics of the Inverse Middle Ear Transfer function favor the TEOAE information associated with the mid octave frequencies (Kemp, 1980;Hatzopoulos, 1995)
