Straight Walls - Barriers
Walls can be used as standalone noise barriers or as part of an enclosure.
Partial Enclosures / Shields
Using corner joiners, a right angle can be formed on straight barrier walls to create open acoustic enclosures / shields.
Complete Enclosures
Using acoustic roof panels and access doors, complete enclosures can be made to reduce sound from machinery or isolate staff working in noisy industrial environments.
Vibration Isolation
Where structurally transmitted noise and / or
vibration must be controlled, acoustic enclosures are built upon a floating floor system on vibration isolators.
The isolators used can be tailored to suit individual project requirements.

Laboratory testing
NCC Acoustic Laboratory - A Laboratory Professionaly Committed to Serving Customers
We exert every ounce of our strength to construct a high-end, avant-garde laboratory endowed with autonomous control capabilities. For all bespoke products, be it in terms of specifications, dimensions, or acoustic requisites, prior to entering the mass production phase, we shall enforce rigorous and meticulous pre-production sample testing procedures. Only upon thorough confirmation that all indicators are up to par will we invest a considerable amount of human and material resources to embark on mass production endeavors, thereby effectively guaranteeing that each and every batch of large-scale goods delivered to clients possesses outstanding quality.
The fabricated product samples are positioned within the spacious window of the laboratory and securely fastened through professional sealing measures. Through precise adjustment of the relevant parameters and concurrent utilization of advanced and precise apparatuses for comprehensive and profound testing, it is ultimately ensured that the products can fully comply with the exacting requirements of customers.
As depicted in the illustration, the external noise of the laboratory attains 80.1 dB, while through random measurement, the internal acoustic laboratory drops to 36.4 dB or even lower. The elevated standard of sound insulation not only ensures the accuracy of the experimentation but also furnishes a robust guarantee for the test outcomes.
