In addition, the results from the acoustic reflex decay test suggest that there might be central auditory pathway involvement in the hearing loss observed among the rotogravure printers.
This finding indicates that hearing testing not only could contribute as an early indicator of those who are more susceptible
to the development of hearing loss, but also help identify those who are more susceptible to eventual neurotoxic effects of solvent exposure.
The ideal procedure for studying and assessing the effects of solvents on hearing consists of a complete audiological
test battery.
Nevertheless, the tests used in the present study (pure tone and immittance audiometry) can be useful screening tools when hearing disorders are investigated in industrial populations in which complex exposure conditions occur.
Thus there may be numerous workers with unmet needs concerning hearing conservation.
