Product Information

et al., Perfect and broadband acoustic absorption by critically coupled sub-wavelength resonators, Sci. Rep., 2016, 6, 19519 CrossRef. Uses: beneath or behind appliances or machines, to reduce the transmission of noise and vibrations. Pros: quite affordable, easy to install, hardwearing and effective at absorbing sound as well as moisture. Floor mats for example, may have been installed to reduce unwanted noise yet microscopic gaps between the matt and the adjoining surface can still allow vibrations to occur. Pros: minimal depth to existing structures such as walls and ceiling, easy to install, long lasting.

Conventional methods used for achieving these effects include hanging fabrics from ceilings, placing absorptive material on walls, or making use of specialized room shapes It is installed onto the internal surface of a wall to offer great results in acoustic calibration (softening) and acoustic isolation (conversion).

Materials Used as Sound Absorbers

Uses: used on walls and ceilings as well as any gaps or open spaces such as seams, seal holes and screw holes. You could also try adding lining to walls, such as tapestries or fabrics, as well as make use of sofas and large soft cushions. These essential principles of soundproofing outlined above work independently of each other, but can also complement one another. Cons: need a lot of depth of the material to be effective by itself. Protective breathing gear must be worn as cutting causes slivers which lodge in the skin, or may be inhaled and irritate the lungs. Well-fitting doors and frames with effective use of gaskets will of course be an important part to any success.

The doors must be sealed well and ventilation, if any, needs to be very carefully set up to ensure that there are no leakages anywhere. Conclusion Some common examples where sound absorption is important include school classrooms, sports halls, concert venues, cinemas, theatres and recording studios.Uses: mainly used in door frames, to complement improved sound absorption in conjunction with other soundproofing methods.
