||Hearing loss among operating engineers in American construction industry
||Aug. 2005, Vol.78, No.7, p.565-574. Illus. 53 ref.
||This study examined the prevalence and characteristics of noise-induced hearing loss (NIHL) among engineers operating heavy construction machinery. Demographic and occupational data were collected by means of a self-administered questionnaire and the 623 participants underwent audiometric tests and otoscopic examinations. Over 60% showed hearing loss in the noise-sensitive higher frequencies of 4 and 6kHz. The degree of hearing loss was particularly high among workers who reported long years of working in the construction industry. Average reported use of hearing protection devices (HPDs) was 48% of the time they were required to be used. A significant inverse relationship was found between 4-6kHz hearing loss and use of HPDs.
