Effect of chemical substances on hearing: interactions with noise

While noise is the main cause of occupational deafness, certain chemical substances can produce ototoxic effects that may make the ear more prone to acoustic assault, as opposed to noise alone. They are mainly solvents, asphyxiants, metals and pesticides, widespread in workplaces. In Quebec, over 400,000 workers are exposed to high noise levels, which raises concerns regarding the prevention of hearing impairments.
