Legislation for the Management of Noise Many forms of environmental noise are under statutory control. A key instrument for control is the comprehensive Noise Control Ordinance which was first implemented in 1989. The ordinance controls construction noise, noise from commercial and industrial premises, neighbourhood noise and noise from newly-registered motor vehicles. The Police are responsible for enforcing controls on noise from domestic premises and public places. They handle complaints and assess the noise based on reasonable judgement. The Police are also responsible for controlling noise from intruder alarm systems. The Civil Aviation (Aircraft Noise) Ordinance also controls environmental noise. It requires all subsonic aircraft using the Hong Kong International Airport to be certified as meeting the most stringent standards.
