[Research progress on early biomarkers for occupational noise-induced hearing loss]

The group of works exposed to occupational noise worldwide is constanthy expanding, with hearing loss becoming a pressing issue that poses serious challenges to public health, economic and society. While current clinical diagnosis primarily relies on elevated hearing thresholds, detectable pre-decibel hearing loss damage has already occurred in the inner ear. Therefore, early biomarkers of noise-induced hearing loss are crucial for the early detection of noise-induced hearing loss and the reduction of the risk of hearing imparment in the occupational population. This article synthesizes the latest research progress on early biomarkers associated with occupational noise exposure-induced hearing loss, aiming to reduce disease incidence and protect the health of occupational populations.
