Abstract: Background The purpose of the study is to establish transient evoked otoacoustic emission (TEOAE) contralateral suppression (CS) standardization values for the pediatric population aged 6–12 years using recommended test parameters and a standard application protocol. After conducting basic audiological evaluation of the participants, the TEOAE-based suppression test was performed on the OAE device using dual probes. The CS testing was conducted using a previously standardized methodology and set of parameters. The study sample consisted of 28 healthy children aged 6–12 years (9.03 ± 1.75) with hearing between 0-25 dB HL, including 14 male and 14 female participants. All participants had a healthy hearing system and did not have any additional problems. Data collection and analysis involved the use of standardized test methods and parameters to obtain data. The Otodynamics ILO292-II OAE device was used to conduct the CS test with a double probe, which provided 65 dB pe SPL stimulation and 65 dB SPL noise. Statistical analysis was performed using the Shapiro-Wilk, repeated measures ANOVA, and independent sample t-test. Results The study yielded “standard” suppression averages for children between the ages of 6–12 for the frequency bands of 1000, 1500, 2000, 3000, and 4000 Hz. In addition, the results obtained from children were compared with those obtained from adults. It was found that children exhibited higher suppression values at all frequencies, with the exception of 1000 Hz. Conclusion The suppression results from the non-pathological pediatric group will be available for future suppression studies in different pathological pediatric groups.
