From the noise
pollution angle, the changes in the industry profile over the last 10 to 20
years have been helpful in complementing Singapore’s noise control efforts.
There are now relatively fewer noisy workplaces in Singapore. The incidence
of noise induced deafness has dropped from 10.6 per 10,000 employed persons
in 1976 to 1.2 in 2004.
The average noise levels in workplaces monitored have decreased
progressively in recent years. However, some industries continue to pose
challenges. For example, in metalworking and aerospace industries, as well
as steel mills, exposure levels can be as high as 105 dBA. Noisy processes
that are inherently difficult to control include steel forging, engine
testing, metal cutting and stamping. |
