Noise Pollution Regulations In Singapore

Noise regulations are enforced in Singapore. Depending on the nature of noise pollution, they are handled by various government agencies. Noise pollution regulations in Singapore can be generally classified into five categories:

  1. Maximum permissible noise levels for factories
  2. Maximum permissible noise levels for construction work
  3. Maximum boundary noise emission limits for air conditioning and mechanical ventilation systems in non-industrial buildings
  4. Workplace safety and health (noise) regulations 2011
  5. Miscellaneous offences (Public Order and Nuisance) Act

Maximum Permissible Noise Levels for Factories

NEA (National Environment Agency) regulates the noise levels from industrial operations through setting boundary noise limits for factories premises. The regulation falls under the Environmental Protection and Management Act. There are two sets of requirements depending on the duration of the noise measurement as illustrated in the tables below.

Types of affected premises

 

Maximum permitted noise levels (reckoned as the equivalent noise level over the specified period) in decibels (dBA)
Day (7am-7pm) Evening (7pm-11pm) Night (11pm-7am)
Noise Sensitive Premises* 60 55 50
Residential Premises 65 60 55
Commercial Premises 70 65 60
Types of affected premises Maximum permitted noise levels (reckoned as the equivalent noise level over 5 minutes) in decibels (dBA)
Day (7am-7pm) Evening (7pm-11pm) Night (11pm-7am)
Noise Sensitive Premises* 65 60 55
Residential Premises 70 65 60
Commercial Premises 75 70 65
