An Exploratory Study of Cervical Vestibular-Evoked Myogenic Potential in Users of Personal Listening Devices

The use of personal listening devices (PLDs) is becoming increasingly popular, particularly among young people. Numerous studies have demonstrated that being exposed to PLDs can have adverse effects on the auditory system. Owing to the similarities between the auditory and vestibular systems, it is possible that the negative effects of PLD use may extend to the vestibular system, an area that has not been extensively studied. The study aimed to investigate the impact of exposure to PLDs on the vestibular system, specifically the sacculo-collic reflex assessed by the cervical vestibular-evoked myogenic potential. The current study used a cross-sectional study design. A total of 80 participants were divided into four groups based on the history of PLD exposure. Each group consisted of 20 participants who underwent cervical vestibular-evoked myogenic potential (cVEMP) testing using alternating polarity 500 Hz tone bursts. Analysis of variance (ANOVA) and Bonferroni post hoc test were used to obtain the statistically significant difference among the group. The results showed that the amplitude of p1-n1 of cVEMP was significantly reduced in individuals with longer PLD exposure duration. The study suggests that listening to music through a PLD at high levels of volume controls could be deleterious to the vestibular well-being of an individual. The study highlights the importance of being aware of the adverse effects of using PLDs to prevent potential damage to the vestibular systems.
