Components 1 to 10 can be selected according to your specific needs. For example, you can choose whether to include glass windows or soundproof doors. The soundproof panels can be selected as either removable or fixed. This offers great flexibility, allowing us to customize products that are suitable for your project according to your requirements.

Combination Description

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.

Ventilation Systems 

Ventilation systems can be provided for acoustic enclosures of both personnel and industrial machinery.

Application 

Industrial Manufacturing:	Used to soundproof machines, compressors, generators, and other noise sources to reduce noise levels in the workplace.
Construction Sites	Employed to mitigate noise from construction equipment (such as concrete mixers and excavators), minimizing the impact on surrounding residents or other construction sites.
Transportation Facilities:	Applied around railways, airports, and highways to reduce traffic noise affecting the surrounding environment.
Commercial Spaces	Used in public areas like shopping malls, restaurants, and cinemas to enhance customer comfort and privacy.
Laboratories and Research Institutions:	Utilized in acoustic laboratories and testing rooms to ensure the accuracy of experimental data by minimizing external noise interference.
Residential Areas:	Implemented in neighborhoods to isolate noise between homes, improving living comfort.
Healthcare Facilities:	In hospitals, soundproof enclosures can reduce equipment noise, creating a quieter treatment environment.

Acoustic Door and Louver Door
We have two different series of soundproof doors to meet various noise reduction requirements. For closed spaces where ventilation and pressure loss are not a concern, we can provide professional soundproof doors to fulfill the needs. For situations like equipment rooms or engine rooms, where indoor air circulation and heat dissipation are important, we can provide soundproof louver doors. These louver doors can meet noise reduction requirements while also allowing for proper ventilation and heat dissipation

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.
