Multi-Channel Acoustic System

Hong Kong apartment blockIn virtue of the increasing needs of the residential dwellings, together with limited land resources, residents in urban areas are inevitably exposed to a high level of road traffic noise.  To protect residents in the public / private developments affected by road traffic noise, innovative noise mitigation designs and measures such as acoustic windows and enhanced acoustic balconies have been proposed to alleviate the noise impact.

However, the noise reduction performance of the innovative noise mitigation designs is only determined experimentally with respect to distance and elevated angles from the traffic sources, the opening size, overlapping length, gap width and absorptive material of windows. As such, it does not consider the workmanship of the construction labour which may finally deteriorate the noise reduction performance of the innovative noise mitigation designs. Therefore, a mock up / field test by Six-channel Acoustic Measurement System and Acoustic Camera is indeed decisive for securing the noise reduction performance.

ANewR offers state-of-the-art Six-Channel Acoustic Measurement System and Acoustic Camera which comply with the international standardsBesides, we also provide quality professional services in acoustical consultancy and associated noise measurements.
