Abstract :
This study proposes a segmented average method that combines the derived nonlinear response (DNLR) method and the linear averaging method to increase the reproducibility of transient-evoked otoacoustic emissions (TEOAEs). Twenty normal ears were tested to evaluate the performance. For each ear, two types of TEOAE signals were obtained with the proposed method and with the DNLR method, respectively. Then the reproducibility of these two kinds of TEOAE signals was compared. Results showed that the average reproducibility of the TEOAE signals was much increased with the proposed method.
