A pilot study has been conducted to test and develop suitable services for these workers and their spouses, and to explore the factors causing them to seek (or on the other hand, avoid) professional(More)
A questionnaire of handicap was developed to assess the psychosocial disadvantages attributable to noise-induced hearing loss (temporary or permanent). Sixty-five workers in a metal product plant completed the questionnaire with their nearest relative. A principal-component analysis was applied to the answers. Results show that the disadvantages can be(More)
To date, there has been no validated speech-reading test available for the French-Canadian population. In the context of rehabilitative services for persons with noise-induced hearing loss, it was felt necessary to develop and validate a speech-reading screening test.
