by train noise. New railway projects are required to undergo environmental impact assessments to ensure that the noise impact is properly addressed.

Aircraft Noise

The impact of aircraft noise on almost all residents in the vicinity of Hong Kong International Airport flight paths is within the planning standard. However, there is still concern about the aircraft noise nuisance, especially during evenings and early mornings. The Government is mindful of the concern and will continue exploring and implementing all practicable aircraft noise mitigating measures, details of which are given in Chapter 13 (Transport: section on Aircraft Noise Management).

Noise from Industrial or Commercial Activities

Noise from industrial or commercial activities is controlled by means of noise abatement notices. The EPD serves abatement notices requiring the owners/occupants of premises emitting excessive noise to reduce it within a given period. In 2006, the department handled about 3 400 complaints and served some 80 abatement notices, which led to some 30 prosecutions.

Construction Noise

Noise from general construction works between 7pm and 7am and on public holidays is controlled through construction noise permits. The permits restrict the use of equipment in accordance with strict criteria and ban noisy manual activities in built-up areas. Percussive piling is prohibited at night and on public holidays and requires a permit during the daytime on any day that is not a public holiday. In 2006, some 2 500 permits for general construction work and percussive piling were issued. There were about 50 prosecutions for working without permits or violating permit conditions. ·

The Government has phased out the use of noisy diesel, steam and pneumatic piling hammers. The law also requires hand-held percussive breakers and air compressors for construction to meet strict noise standards and to have 'green' noise emission labels before use. In 2006, about 500 labels were issued.

To deter repeated industrial/commercial and construction noise offences, the Noise Control Ordinance stipulates that the senior management of a body corporate will be held liable for repeated offences committed by their body corporate.

The EPD also introduced a new Quality Powered Mechanical Equipment system to promote the use of more environmentally friendly construction equipment and to facilitate the construction noise permit application process.

Intruder Alarm and Neighbourhood Noise

The Police Force handles complaints about intruder alarms and neighbourhood noise from domestic premises and public places. In 2006, the police dealt with some 3 000 complaints.
