Pre-Assembled Sound Enclosures

Pre-Assembled Sound Enclosures

Noise enclosures offer a high performance and cost effective alternative to field built solutions. Pre-Assembled sound enclosures use conventional construction materials or modular acoustical components. eNoise Control pre-assembled noise control structures are the ideal solution for projects with limited time, space, or budget. By controlling every aspect of the design and assembly in our factory, we can guarantee high levels of mechanical, structural, and acoustical performance.


There are many design possibilities of eNoise Control pre-assembled structures. The only limitations are shipping and handling restrictions. Consider the following “Drop In Place” noise control solutions.

Construction Basics

The construction method of the pre-assembled enclosure depends on the design and performance criteria specified. For medium duty industrial and commercial applications, the design is based around using our modular acoustic panel system. In these situations, we incorporate unitized assembly methods and floors when required. This can be as simple as assembling a modular panel enclosure to a unitized base frame or floor with fork-lift capability. A more robust structure begins with a complete, fully welded structural sub-frame. On this, walls and a ceiling are constructed with pre-engineered modular components or built-up insulated construction with steel skins. This type of structure provides high acoustical performance and resistance to sever environments.
