Acoustic Insulation is utilised to cut down the amount of sound in a particular area. There are a few ways to cut down sound: making the distance between source and receiver greater, utilising noise reflectors to swallow the energy of the waves, using things like structures like a baffler, or using great anti-noise sound generators.
A couple of sound proofing issues will need to be thought about when designing acoustic solutions - to make the sound better in an area and lower sound dispersal to/from rooms that are next to each other or into the outdoors.
Sound proofing can swallow unsolicited indirect sound such as reflections that cause echoes and resonances that cause the sound to be prolonged. Acoustic Insulation can limit the transfer of unwanted direct sound from the for example stereo to an someone or something that doesn’t want to hear it, through the use of distance and placing things in the path of the sound.
A room in a room is one way of achieving Acoustic Insulation where isolating sound and preventing it from sent to the outside world where it may be not wanted.
Home Acoustic Insulation is designed to lower or stop the effects of outside noise. The main thing with home sound proofing in already built homes is normally the windows. Curtains can be used to muffle noise either through the use of lumpy fabrics or using air chambers which are commonly known as honeycombs. Single, double and triple honeycomb options achieve much greater degrees of sound proofing.
The problem with curtains is there isn’t a seal at the edges, although this may be partially solved by using sealing props, such as hook and clips, glue, magnets, Double Glazed windows create a greater sound damping than one paned window. More sound can be cut out by putting in a second slide window inside the house. The outside window stays where it is, while a slider or hung pane is put in within the same wall space
Companies often use Acoustic Insulation technology. Bars, Colleges, and Hospitals use architectural acoustics to lower sounds for their users. Office buildings often make open plan spaces less noisy for staff who use the telephone
Vehicle acoustic insulation is designed to lower or stop the effects of outside noise, mostly the engine, exhaust and wheel noise on the road. The car environment restricts the levels of materials that can be used, but combinations of other sound proofing methods are common.
