Occupational noise exposure and hearing loss symptoms among construction workers / Muhammad Rafik
Forty four noise exposure samples were collected at low-cost apartment building construction from two different construction trades: ironworkers and bricklayers. The noise exposure level was measured using personal noise dosimeter, whereas hearing loss with other health effect was measured via quest...
