Noise Pollution

NEA regulates noise levels from construction sites and industrial operations using a set of permissible noise limits. NEA also sets noise emission standards for vehicles.

Recognising that Singapore's continued rapid development - from new residential and commercial structures to improved and expanded transport infrastructure - brings with it some inevitable inconveniences, NEA works together with industry and the public to establish acceptable levels of noise.

Details on NEA's permissible noise levels for construction sites and industrial premises are as follow:
