The Association of Blood Type Differences and Signal-noise Ratio in TEOAE and DPAOE in Individuals with Normal Hearing

OpenAlex İngilizce

Objective: The aim of this study was to investigate whether ABO and Rhesus (Rh) blood type systems are associated with distortion product otoacoustic emission (DPOAE) and transient otoacoustic emission (TEOAE) amplitudes, with the hypothesis that blood types affect hearing thresholds.Methods: Seventy participants with normal hearing, aged 18-26 years, with normal tympanometry and otoscopic examination findings, were included in the study.TEOAE and DPOAE tests were conducted on all participants.Results: The Rh factor did not significantly affect the OAE results.It was found that the TEOAE amplitudes of blood type B at 1.4 kHz in the left ear were higher than those of blood types A and AB.The amplitude of AB blood was lower than that of O, A, and B blood types at 2 kHz.Conclusion: Our study results did not indicate a consistent pattern for a specific blood type, in contrast to previous findings.Additional research is required to investigate the potential correlation between hearing function and ABO and Rh blood types.
