An experiment in mice opens the door to the creation of a drug capable of minimizing hearing damage

Researchers from the University of Pittsburgh have discovered a biological mechanism for hearing loss caused by loud noises. The study, published in PNAS, revealed a correlation between hearing loss and the presence of zinc in the inner ear. Loud noises cause a large release of zinc that disrupts normal cell communication, leading to damage. The team is now developing a device that can prevent hearing loss. It involves using a gel that traps the excess zinc released in the auditory canal after exposure to noise. Further experiments are needed before the treatment can be applied to humans. Despite this, the researchers stress that prevention, such as using ear protectors in noisy environments, remains the best cure.
