Title Extended high-frequency audiometry and noise induced hearing loss in cement workers
Bibliographic information June 2008, Vol.51, No.6, p.452-462. Illus. 21 ref.
Abstract It has been suggested that extended high-frequency audiometry (EHFA) might be more sensitive than conventional audiometry in detecting early signs of hearing impairment. The usefulness of this method was investigated in noise-exposed workers from two Italian cement plants. Conventional frequency audiometry (0.25-8kHz) and EHFA (9-18kHz) were compared in 184 noise-exposed and 98 non-noise-exposed workers. Both methods showed significantly higher hearing threshold levels in noise exposed workers for most of the tested frequencies; however, the differences were more marked for EHFA, especially in young exposed workers. Significant differences in the extended high-frequency range were detected also in the subgroup of noise-exposed workers with normal findings at conventional audiometry.
