Thesis Summary

Aim: To investigate whether listening to music at high levels through headphones contributes to hidden hearing loss (HHL) in young adults, and whether listening effort and cognitive skills differ according to headphone exposure.

Findings: Signs of noise-induced cochlear synaptopathy were observed in the high-risk group; as the signal-to-noise ratio decreased, listening effort increased and the P300 amplitude decreased significantly. No significant difference was found between the groups on cognitive tests.

Conclusion: The findings support the hypothesis that listening to loud music through headphones may lead to hidden hearing loss.
