Noise emitted by drop hammer piling machine and workers' noise exposure

Hammer driven piling machine is the typical piling equipment in Malaysia, according to previous research on piling activities more than a decade ago more than an average of 90 dBA was recorded during the occurrences of piling activities at a common construction site that disturbs the neighbourhood....
