Hearing loss among miners claiming compensation.

Otological and audiological evaluations were performed on 278 miners claiming compensation for noise-induced hearing loss (NIHL). Of the total sample, 28.7% had to be excluded as cases of nonmining NIHL. Of the cases of diagnosed as NIHL, approximately 50% showed an actual hearing impairment as based on a low fence of 25 dB for the average hearing levels at 0.5, 1, and 2 kHz, and 63% as based on the average hearing levels at 0.5, 1, 2, and 3 kHz for exposures of 15 to 49 years. No significant difference in NIHL was apparent except at 2 kHz between subjects exposed to intermittent vs intermittent-continuous noise. It was difficult to differentiate NIHL from sensorineural losses of other causes and impossible to apply an adequate correction factor for presbycusis.

Critical view on audiometric screening in school.

After examination of the factors affecting the validity of audiometric tests in schools, screening programs are seen as having little value as a preventive measure because of their failure to reach their primary purpose, the early discovery of hearing loss and ear disease. The philosophy of screening is challenged and an approach of total prevention proposed that puts much more emphasis on primary prevention measures such as the control of determinants of ear disease and hearing loss in school-children.

[Stapedial reflexes in presbyacusis and occupational deafness].

Acoustic reflex thresholds were measured on 251 subjects (418 ears) with varying degrees of sensorineural hearing loss. The subjects are divided in three groups according to the pathology involved: presbyacusis and noise-induced hearing loss and combined hearing loss caused by both presbyacusis and noise exposure. The dynamic range of hearing was found to be reduced for all cases and at all frequencies. The decrease in dynamic range was proportional to the severity of the hearing loss. The sensation levels of the acoustic reflex thresholds seem to be dependent on the degree of hearing loss and not on the aetiology. Practical conclusions are drawn concerning the prediction of thresholds of hearing and the diagnosis of recruitment based on reflex measurements.
