Though the terms soundproofing, sound isolation and sound absorption are used as more or less synonymously – but as a matter of fact their meaning as well as purposes are all different and if you are working on industrial soundproofing projects or need to find solutions for sound proofing requirements – then understanding the differences between them is of some importance. The sound proofing materials that you will find available in the market all belong to one category and another and which one of them you need to use should be determined only after expert checking and advises from a trusted Commercial Soundproofing in Sydney.
Sound proofing
Sound proofing is actually the process that prevents sound from travelling through a particular surface and stops them from both escaping from and entering in a space. Naturally spaces or rooms those are sound proof emit less noise. Acoustic barriers are made from denser substrates than those of the acoustic absorbers and actually serve as a barrier between the sound and areas outside. How well they can prevent sound waves from transmitting through a particular surface is determined by their Sound transmission Class rating.
Sound absorption
On the other hand sound absorption materials are softer and less dense materials those have open cell structures. Such cell structure makes those materials soft and pours and sound waves entering those pours won’t exit again. They are actually trapped or absorbed by that foam like materials. Sound absorbing materials can not actually block sound waves from entering or exiting a space and can only improve the acoustic qualities within a particular area. Just like the sound proofing materials, sound absorbers are also given a Noise Reduction Coefficient rating that is an indicaton of how good they are in absorbing sounds.
Different types of sound proofing materials
An extensive variety of sound proofing as well as sound absorbing materials are now available in the market those are suitable for various different types of applications. Moreover they do also have different best usage conditions and scenarios. All the different types of materials used for Industrial Soundproofing or other similar purposes can be grouped in the following for your better understanding:
- Acoustic Isolation membranes
- Open cell type cavity insulation products
- De-coupling materials
- Acoustic flooring, panels and fabrics
- Acoustic foams
- Sound proof doors and windows
Considering the multitude of products available, finding the right material for best possible results require extensive knowledge on those products as well as on the principles of sound proofing and this cannot be expected from an amateur or a layman. There are professional acoustic checking companies in Sydney who can inspect a commercial and industrial place for identifying the sources of the noise there and suggest steps accordingly.
