| Abstract |
Railway track maintenance work is often noisy, exposing workers to noise levels often exceeding 90dB(A) and making the wearing of ear protectors necessary. At the same time, many track maintenance tasks take place without interrupting the rail traffic. The ability to hear acoustic signals warning of the impending arrival of a train is vital to workers' safety. Under these conditions, hearing protectors are perceived as an additional risk of not hearing the alarm signal. This study was able to demonstrate that hearing loss among track maintenance workers is no greater than among the general population of same average age. Furthermore, testing in laboratory conditions showed that wearing hearing protectors did not detract from hearing the acoustic alarm signals. However, these findings need to be confirmed in field tests. |
