  7. 5. Risk of hearing loss from combined exposure to hand-arm vibrations and noise

    Författare :Hans Pettersson; Lage Burström; Tohr Nilsson; Kerstin Persson Waye; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hearing loss; noise; hand-arm vibration; combined exposure; vibration induced white fingers; Raynaud s phenomenon; Occupational and Environmental Medicine; arbets- och miljömedicin;

    Sammanfattning : Hearing loss from noise exposure is one of the most common occupational injuries, and exposure to vibrations may increase the risk of noise-induced hearing loss. Earlier cross-sectional and longitudinal studies found an increased risk of noise-induced hearing loss among workers with vibration-induced white fingers (VWF) symptoms compared to workers without such symptoms.
