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.

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.

•Industrial sound insulation room applications include:
•Diesel engine generator set, with cost-effective, durable, and high-performance casing to protect employees and communities from the impact of engine radiated noise
•Compressor housing, used for large industrial compressors driven by gas engines and electric motors, for process, power, and gas delivery applications
•The excellent sound insulation function of the personnel rest area in the factory isolates employees from the noisy workshop environment, while the integrated lighting, electrical, and HVAC systems create a comfortable and efficient working environment
•Control rooms and operation forums, where residents are protected from hazardous production areas such as forging and smelting plants. Modular ™ The soundproof panel has a ballistic and fire rated structure, as well as a heavy-duty solid steel casing, providing physical and acoustic protection
•Vehicle and component testing units generate high noise levels and require isolation from engineering and production personnel. IAC acoustic testing units are typically used for product development and production testing applications, such as electronic audio component manufacturing, automotive development and testing, and material destructive stress testing in the healthcare industry
Product advantage
•Reliable sound insulation performance: Products tested in the laboratory have guaranteed sound insulation/absorption performance (non theoretical calculation)
•Reduce sound energy: The absorbing surface minimizes reflected noise and reduces parallel barriers•Corrosion prevention: Equipped with rainproof and rust proof material selection and surface treatment process
•Modular plugin: The surface is flat and can be treated with a wide range of options, resulting in landscape integration
•Structural design: Possess the ability to design steel structures, capable of calculating wind and snow loads
•Rapid organization: composed of prefabricated components, capable of rapid, non welded on-site assembly
For each individual project, it is possible to select a panel design which has the required sound transmission loss
and sound absorption ratings.

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.
