To tackle construction noise (including renovation noise) issue directly, there is a need to adopt the state-of-the-art quieter construction methods and equipment, and noise mitigation measures for construction projects.

The data show that the sound pressure level of noise generated using quieter equipment and methods is significantly lower than that of using traditional equipment and methods

 

Noise reduction for some mitigation measures for reference.

Mitigation Measures

Noise enclosure for underground construction works

Use of acoustic enclosure for stationary plant can achieve a noise reduction up to 20dB(A) easily.

(Wilson Acoustic) Noise barrier

An effective way of reducing noise is to install a purpose-built barrier between the noisy equipment and the noise sensitive receiver.
