The aim of this pilot study was to investigate the feasibility of an epidemiological study on the effects of occupational exposure to styrene and noise on the auditory system. An audiological test batter, styrene and noise exposure assessment protocols and a questionnaire were evaluated by testing 14 exposed workers and a group of 10 unexposed controls. The questionnaire included questions on work history, non-occupational solvent and noise exposure and medical history. The test batter comprised pur-tone audiometry, immittance audiometry, distortion product otoacoustic emissions, psycho-acoustical modulation transfer function, interrupted sppech, speech recognition in noise, and cortical response audiometry. Exposure assessment included gathering data from interviews and company records, site-measurements for different work tasks and divisions of the company and videotaping using the PIMEX-method.
