Modular Acoustic Enclosures for Industrial Noise
Everyone knows that manufacturing spaces can get noisy. What’s worse, this noise is often more than just unpleasant, it can lead to safety issues, communication problems, and sometimes even OSHA violations.
Such noise can be from many different sources, like generators, CNC machines, compressors, and a whole host of other industrial equipment.
But wherever it comes from, it can make it difficult for your employees to perform at their best. By containing the clamor with modular acoustic enclosures, you can effectively stop the noise right where it’s coming from.
In this article, we’ll discuss what they are, why they’re used, who uses them, some of their customization options, and more.
What Is a Modular Acoustic Enclosure?
A modular acoustic enclosure is a prefabricated covering or structure built to reduce loud noises. They can be used to cover particularly noisy machinery or equipment, or else be used to create a quiet environment in an otherwise busy space.
The acoustic enclosures are “modular” in the sense that, instead of being built with drywall or concrete on site, they are prefabricated in a factory beforehand, delivered in sections, and then assembled quickly at the job site.
These structures can either stand by themselves or connect to existing buildings, and they’re used in any industry where loud noise has become a problem. Some notable examples are manufacturing, aerospace, and oil & gas. They aren’t strictly limited to heavy manufacturing though either, as even a basic e-commerce warehouse might need quiet rooms.
They are a quick fix to get noise levels under control, especially without having to stop important work or change your layout.
Why Use Modular Acoustic Enclosures?
One of the biggest advantages of modular acoustic enclosures is their speed, as we hinted at already. Because the panels are built off-site within a factory (essentially in advance), and then shipped to be assembled, the actual installation process is finished within days rather than months.
Another benefit is their flexibility. With modular, you can expand or relocate the enclosures if you need to do a layout adjustment, or even a move. The panels are mostly of similar size, and each can be disassembled and reassembled elsewhere.
Furthermore, in many cases, modular designs cost less than traditional construction. The latter is notoriously expensive in terms of labor and materials. Since modular buildings are made in a factory, materials are used far more efficiently. What’s more, since they can be reused and moved, they have a much better ROI (especially for growing businesses).
Workers will appreciate them as well. Nearby employees can focus better without loud noises, in addition to avoiding unsafe levels, which could damage their hearing permanently.
What Are Modular Acoustic Enclosures Used For?
Modular acoustic enclosures are in many different industries. Some common uses include:
- Generators and compressors
- CNC machines
- Transformers
- Packaging lines
- Control rooms
- Operator booths
- Tall walls / barrier walls in manufacturing spaces
Materials Used in Modular Acoustic Enclosures
Given all the different uses of them, acoustic enclosures are not going to use the same materials across the board. The materials will be different depending on how loud the noise is, and to what degree you need to lower it.
Here are a few different materials/construction features used for them:
- Panel Materials: Often made of steel or aluminum exterior, with sound-absorbing cores such as wool, fiberglass, or foam.
- Panel Thickness: Common sizes include 3″ and 4 5/8″, depending on required acoustic performance.
- STC Ratings: Panels rated by STC: STC 31 for moderate noise, and STC 45+ used for high-noise equipment or OSHA compliance.
- Acoustic Doors: Doors with gaskets and insulation help prevent sounds from entering/escaping.
- Windows: Special laminated or double-glazed windows allow you to see inside without permeation of sounds.
- Safety Features: Fire-rated walls are also available, and can help you stay in compliance with fire codes.
This is by no means an exhaustive list. We always recommend speaking directly with a manufacturer to learn more about construction options.
Customization Options for Modular Acoustic Enclosures
These enclosures can also be fully customized to fit your operation, regardless of whether it’s for a basic machine enclosure or a building with multiple rooms. Some common customization choices include:
- Layouts: At MachineEnclosure.com, all our layouts are fully customizable. This means we can make partial enclosures, full enclosures, spaces with many rooms, or whatever else you need.
- Entry Points: Doors and access points can be added as needed. We have sliding doors, roll-up doors, removable panels, service hatches, and more.
- Material Openings: Cutouts in the enclosure can be made for conveyor systems, piping, or wiring.
- HVAC Systems: We can also add integrated or full HVAC systems; this may be especially important if you’re covering machines that need to operate within narrow temperature ranges.
- Integrated Electrical: Raceways which carry wiring for lighting, power, and data can be placed strategically to support your equipment or team.
Of course, this is also only a partial list of the many features and customization choices that can be added.
The Bottom Line
Modular acoustic enclosures are an easy way to reduce noise at your location, even if you’re in a busy industrial or manufacturing space. They can be installed fast, can move when you need them to, and help you improve the well-being of your workers.
