Abstract
Introduction: In order for a diagnosis of Occupational Hearing Loss (BK-no. 2301) to be made certain criteria must be fulfilled to establish that the hearing loss is occupational in origin. This work compares 2 groups, those who fulfil the criteria (BKE) and those who do not (BKNE). Methods: A 100 consecutive reports ("Lärmgutachten BK-no. 2301") written by the authors were examined retrospectively. These recorded audiometric examination, an analysis of any tinnitus and noise exposure plus use of hearing protection. Pre- and post-noise exposure status together with an expert assessment of work limitations was made to produce a 7 point score. Results: 67% of the group fulfilled the conditions for occupational hearing loss (9% were entitled to compensation). In the BKE group 82% showed typical audiometric signs of noise damage with 75% of them fulfilling at least 6 criteria of occupational disease no. 2301. Tinnitus typical for noise exposure was found in 26%. Discussion: A 7 point score could be useful in the future as a method of helping distinguish hearing loss and tinnitus from occupational as opposed to other causes.
