Acoustic enclosure


Acoustic Enclosures 

Acoustic enclosures are designed to reduce the noise levels radiating from fixed plant in factories and industrial estates. The need to reduce noisy machinery is important in helping maintain an acceptable indoor level of noise at work, as well as reducing the environmental impact of outdoor noisy plant.
We can offer full acoustic enclosure solutions as well as partial solutions, such as acoustic barriers, depending on your needs. Full Acoustic Enclosures work best in severely noisy environments and can be fitted with access points for maintenance and operation. Partial solutions such as Acoustic Barriers can work well in reducing direct impact noise on surrounding neighbours.
In addition to this we can also offer
• acoustic doors,
• acoustic windows and
• acoustic booths
All form part of our acoustic enclosure range. Available in a galvanised as well as stainless steel and can be finished by polyester powder coated to any standard RAL colour.

Although acoustic enclosures often look similar to sheet metal guards and indeed can often fulfill the same physical function as them, their principle purpose is to prevent high levels of reflective noise and reverberation coming from specific types of machinery. Such guards have become increasingly important in factory environments, as legislation seeks to ensure that workers are protected from noise induced hearing loss to the same extent as they are protected from other machine hazards.
How acoustic enclosures work
In addition to the basic sheet metal structure, an acoustic enclosure also contains sound-deadening and sound absorbent materials. These materials can vary dependent on the application, with a factor determining them being whether or not the application is wet or dry.
Specification features of acoustic enclosures depending on application, these can include:
• Exhaust gas removal for combustion engines
• Air inlet drive for combustions with filtered air optional
All our acoustic enclosures allow for access for operators and maintenance personnel, with this access controlled by interlocks where necessary. Indoor and outdoor applications for acoustic enclosures are varied and include those for both indoor and outdoor machinery, with examples including:
• Air compressors
• Diesel and gas generators
• Cable stranding machinery
• Metal cutting machines
Installation of acoustic enclosures
As with all the machine guards we design and manufacture at Procter Machine Guarding, we offer a installation service for acoustic enclosures. We have our own team of highly trained and very experienced fitters, and can carry out installations to fit in with the customer - e.g. weekends, overnight and other factory down-times.

Acoustic Enclosure Solution
A full enclosure will offer significant reduction to the noise levels radiating from items of plant. This can be highly successful in reducing the background noise of all ready noisy environments.
Benefits of a full acoustic enclosure:
• Significantly reduce noise levels typically between 15 to 50 dB (A) depending on the construction and design.
• Help reduce indoor factory noise levels to conform to the Noise at Work Regulations.
• Remove the need for mandatory PPE.
• Can be designed to suit a wide variety of plant and situations.
• Indoor and outdoor installations, as well as painting available in any standard RAL colour.

Acoustic Barriers Solution
Acoustic Barriers are required in order to protect commercial and residential estates from noise sources such as outdoor plant, railway and roads as well as finding useful application in industry both protecting the internal work environments, where full acoustic enclosure solutions are not practical.
Benefits of an acoustic barrier:
• Available in any length from short indoor applications to long outdoor projects.
• Significantly reduces direct component of noise levels from source to receiver.
• Significant high frequency noise reduction.
• Can easily be relocated for expanding areas.
Acoustic Enclosure Details
At Acoustics our enclosures and made up of acoustic panels and supporting steel work. The acoustic panels comprise of sheet steel, either galvanised or stainless finishes, perforated sheets and mineral wool infill. The enclosure can be designed to incorporate access such as removable panels and acoustic doors. In addition to this we can also include acoustic louvres if overheating of enclosed plant is to be an important consideration.





soundproof enclosures are designed to isolate noisy equipment from employees or adjacent neighbors. For the most effective sound isolation and sound control and noise control, the following features and criteria need to be considered:
1. Accessibility For Production & Maintenance
2. Access Doors For Controls, Personnel or Equipment
3. Proper Ventilation to Prevent Heat Build-Up
4. Viewing or Observation Windows
5. Power Supply to Equipment/Receptacles
6. Lighting Requirements – Standard/Explosion-Proof
7. Enclosure With Floor and/or Vibration Isolators
8. Penetrations
o Intake Duct/In Feed
o Discharge Duct/Out-Feed
o Conduit/Piping
o Ventilation/Silencers
