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.

Diesel Generator Sets
Designed for industrial power generation and backup power systems, effectively reduces engine radiation noise to protect factory workers and surrounding communities.
Industrial Compressors
Engineered for high-noise equipment in natural gas transmission, chemical processes, and power plants, the soundproof housing ensures compliant noise levels and supports 24/7 continuous operation.
Factory Staff Rest Areas
Provides acoustic protection for temporary breaks near workshops and shift worker relaxation zones, isolating noise to create a quiet and comfortable working environment.
Industrial Control Rooms
Offers dual physical and acoustic protection for high-risk areas like forging and smelting plants, safeguarding personnel safety and operational environments.
Precision Testing Chambers
Tailored to automotive NVH testing, medical device calibration, and electronic component verification, it delivers low-noise testing environments to ensure accurate data reliability.
Technical Assurance:
Laboratory - measured data combined with modular steel structure design ensure performance and safety.
Scene Coverage:
From isolating high - noise equipment to staff rest areas and precision test cabins, it is suitable for all industrial scenarios.
Cost - effectiveness:
Quick installation and corrosion - resistant and durable features reduce long - term maintenance and operation costs.
Reliable sound insulation performance:
The sound insulation/absorption performance of products tested in the laboratory is guaranteed.
Corrosion prevention:
Rainproof and rust - proof materials and surface treatment processes are adopted.
For each individual project, it is possible to select a panel design which has the required sound transmission loss and sound absorption ratings.

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.
Testing Report
All Reports can meet the American Standars, the sound testing we did with Intertek
NCC acoustic Panels are multi-purpose, permitting air to flow, whilst shielding the environment from unwanted noise.
Our louvres are available in an array of standard modular sizes, meaning that a wide range of performance requirements can be met. By using our range of acoustic louvres, it overcomes architectural consistency issues, especially where space is limited.
All our packing with Rubber clip board,don't need to do fumigation.
