Acoustic Housings
|
One of the most important assets to a company are it's workforce and their well-being.
If your workforce are at risk then it is important to ensure the necessary changes are
made to prevent any future issues. In a situation where the working environment produces
a lot of noise, which can be dangerous to anybody within the immediate vicinity it is
important to reduce the potential threat. This usually encorporates some variation of
an acoustic housing or spray booth, which is designed to eliminate any of
these noises.
The size of and shape the acoustic housing will be dependant on a number of different
crucial factors:
|
1) Purpose - the reasons for the acoustic housing and it's application.
2) Level of Noise - the volume of the noise, which is being produced.
3) Size & Shape - the proposed size and shape of the proposed solution.
|
|
These are the most important factors we take into consideration when designing and manufacturing
any of the acoustic housings we develop. We specialise in the design of bespoke acoustic housings,
whose size range from table top to larger than an average room. We have had experience in manufacturing
acoustic housings for factories, laboratories and even mixed use developments such as a retail mall & apartment complex.

How Does An Acoustic Housing Function?
Imagine the situation where a machine that is a source of a loud, deafening noise is unprotected and is situated
in a workspace where there are constantly people passing through the area. Even with the appropriate protection
(headphones, ear plugs.. etc), this environment is going to be a hazard to each of the workers and may require the
use of an acoustic booth or housing to reduce the noise levels and make working conditions safe.
Acoustic housings are specifically designed structures which are built up from acoustic panels that are used to absorb
any sounds and prevent it escaping. They have a relatively simple construction and they do their job effectively.
|
The above diagram is not to scale but it shows the basic materials and construction of the acoustic panel. The panels
are made from galvanised steel with a perferated steel mesh front and the center of the panel is filled with mineral wool
, which is perfect because of it's sound absorbing properties.
Imagine there is a theoretical source of noise, which for the example above is a cube. We would design and build a construction, taking into consideration the different crucial factors from above until
we have a structure which is going to reduce the level of noise generated.

Although the acoustic housings need to have an almost airtight construction to achieve maximum noise reduction, it is also important to ensure that the structure has a method of ventilation. This is usually
two simple intake and outtake ventilation ducts one situated at the bottom and one at the top of the acoustic housing. The natural intake of cool air at the bottom and the outtake of the hot air that has risen
due to natural airflow.
|
|
The intake and the outtake vents have a minimal impact on functionality of the acoustic housing by minimising the
possibility of air escaping from the structure. They are reasonably closed channels which means they do not allow noise to
escape.
