Determination of Mining-Induced Hearing Loss with Otoacoustic Emission Method at Tki-Eli Lignite Field

摘要

Noise at the working environment is highly affecting the human health, especially in mining. Continuity of this noise causes hearing loss of miners. In this study, hearing loss based on noise is researched by audiometry and otoacoustic emission on casual staff of TKi-ELI coal mines. The difference of this method is taking the otoacoustic emission measurements before audiometry measurements. In 2007, audiometry and otoacoustic emission measurements were made on 639 miners at Ege Lignite Enterprises. It is determined that conductive hearing loss had seen at 32 miners and sensorineural hearing loss had seen at 83 miners. It was decided to dispatch 9 miners to Occupational Diseases Hospital after making tests to these 83 miners at Soma State Hospital. It is revealed that these 9 miners shouldn't be allowed to work at loud environment according to the first report of Occupational Diseases Hospital. The detection of the possible and occupational disease group hearing loss has become very easy with this method.
