Does the short-term exposure to radiofrequency electromagnetic field originating from mobile phone affect auditory functions as measured by Acoustic Admittance and Evoked Otoacoustic Emission tests?

Abstract

Overview

Mobile phones are a significant source of radiofrequency electromagnetic field (RF-EMF). The sensitivity of the inner ear's sensory hair cells to various factors makes the potential impact of mobile phone usage on auditory functions a critical area of study.

Aim

The study aimed to evaluate the effects of a 15-minute simulated phone call on human hearing through Transient Evoked Otoacoustic Emission (TEOAE) and Acoustic Admittance Testing (AAT).

Material and Methods

• The study was conducted on 23 healthy male volunteers.
• Each participant was tested before and after the simulated phone call using TEOAE and AAT.
• Parameters such as static compliance of the tympanic membrane, middle ear pressure, and acoustic reflex thresholds were analyzed.
• The study also divided participants based on their self-reported sensitivity to RF-EMF from mobile phones.

Findings

No significant differences were observed in the auditory tests before and after RF-EMF exposure, including both exposed and non-exposed ears. Additionally, EMF sensitivity reported by individuals did not alter the outcomes.

Conclusion

The short-term mobile phone RF-EMF exposure did not significantly impact auditory functions. Despite these findings, the study underscores the need for further research with varied signal frequencies and larger, more diverse samples to generalize results effectively.
