Multi-Channel Acoustic System

Aiming high and far is the beginning of development. Developing digital solutions for environmental assurance is no easy task involving determination, review, test, and integration. We act on development to acoustic visualisation on preventive maintenance. The past manual measurement method takes money and human resources, and time. Our system’s most significant advantage is to solve the manual scheduled inspection and maintenance problems by identifying potential flaws without interrupting regular operation. It is a combination of acoustics and vision analytics technologies. The working concept is straightforward: identifying the noise with the acoustic camera and a CCTV at a specific spot, detecting abnormal machine running and tracks by identifying the high-frequency noise.

why multi-channel monitoring

Artistry defect causes sound leakage

Abnormal sound represents an operational defect

Noise is omnidirectional and reverberant. It is difficult to identify the sound source

The noise reduction performance of the innovative noise mitigation designs is only determined experimentally concerning distance and elevated angles from the traffic sources, the opening size, overlapping length, gap width and absorptive material. We cannot be sure of the actual performance in a real-world living situation.


ANewR offers a state-of-the-art Six-Channel Acoustic Measurement System and Acoustic Camera, which comply with international standards. Besides, we also provide quality professional services in acoustic consultancy and associated noise measurements. All noise measurements are undertaken according to the most rigorous QA procedures and methodologies of the international standards to ensure quality data for our Clients.
