Background
A standard method and parameter study were performed for the contralateral suppression test. Purpose Our study aimed to determine the contralateral transient-evoked otoacoustic emission (TEOAE) suppression test method and stimulus–noise parameters that have a standard procedure and will enable the efferent system to be easily evaluated in clinics. Research Design This study was conducted in two parts with two different groups of participants as a within-subjects design. In the first part, the signal-to-noise ratio at which maximum suppression obtained was investigated with 29 participants. In the second part, the optimal contralateral noise presentation method (in terms of noise-time or noise-sweep) was examined with 21 participants. Study Sample In the first part 29 young adults aged between 18 and 32 (23.03 ± 2.84), 20 females and 9 males, and in the second part 21 young adults aged between 19 and 34 years (mean age: 23.71 ± 3.48 years), 16 females and 5 males, participated in the second part. All participants had normal hearing. Data Collection and Analysis To obtain maximum OAE suppression, different parameters were tested with the Otodynamics ILO292-II OAE device at both parts of the study in a double-walled audiometric test booths. Multirepeated analysis of variance, pairwise comparison, Friedman test, and Wilcoxon signed-rank tests were used for statistical analysis. Results In the first part, maximum suppression was achieved at 65 dB peSPL (decibel peak-equivalent sound pressure level) TEOAE stimulus and 65 dB SPL broadband noise. In the second part, maximum suppression was obtained in noise-time method with 30 seconds “duration.” Conclusions To provide standardization in clinics, it can be recommended that the contralateral suppression of OAEs was measured at 65 dB peSPL TEOAE stimulus and 65 dB SPL broadband noise in the linear stimulation mode with Otodynamics ILO 292-II double-probe OAE device. To obtain maximum suppression, the noise-time method with 30 seconds duration can be used. |
