Relevant noise levels and representative population exposure to the six identified noise source have been monitored and analysed in this report. In general, the majority of population are exposed to noise levels of below 65 dB(A) and below 60 dB(A) generated from Cargo Handling Area, Open Storage Area, Industrial Estate, Container Trucks Parking & Repair and Container Terminal during daytime and evening/night-time respectively. For Industrial/Residential Interface, due to small separation distance between the population and noise source, the highest noise level was recorded and a relatively larger proportion of population was exposed to over 65 dB(A) during daytime when compared to other activities.

In general, the larger the size of the noise source of a particular activity, a larger proportion of the population will be exposed to higher noise levels.

To facilitate the incorporation of the present survey findings into the SUSDEV 21 Study, the exposure of population to noise from the selected non-transport related sources was deduced. It was estimated that some 435,000 people who live near to the six surveyed activities would have a higher likelihood of being exposed to noise. Among them, some 60,000 people would have a higher possibility of being exposed to a higher level of noise.
