Transsonic isolation is the method by which a room or instrument is taken away from from outside, and usually unwanted, noise. To achieve this requires a decent understanding of how sound travels. Most people understand that sound trip through air, we know this intuitively because we can discover people when they are talking and we can shout to them when further away. It is a relatively simple concept to tackle air terme noise. We all understand that closing a door to a room or space or constructing a wall between rooms will not less than reduce the amount of sound that penetrates that room., having said that what fewer people understand is that sound travels thru materials and structures as well. Think about someone knocking for that wall or door. Even though it is solid, you possibly can still hear the sound of the knock quite clearly. This shape borne sound can be harder to understand, isolation acoustique and finish.
Air borne and structure borne sound
Usually, a strong acoustic isolation solution must tackle both of these problem areas. On the surface, the solution is quite simple. Two things are known to stop reasonable: space and mass. Mass is required to stop the air-borne sound but because solid objects also conduct sound, turning it into structure borne sound, you also need to introduce ground. This gives rise to some common acoustic isolation techniques, where you have got to a layer of material followed by an air gap and next another layer of material. It is an effective approach but it requires a deep understanding of how sound works in order to create the suitable acoustic isolation solution.
Noise absorption or reduction
Area of complexity is how different materials interact with audio. A solid object can either absorb or reduce noise. Audio reduction refers to the deflection or blocking of sound electrical power. The best materials to achieve this are high density, rigid and large. Softer and less dense materials, on the other hand, easily transmit nicely are not suited to blocking or deflecting noise. These sleeker materials, however , are often more effective at absorbing sound. Very soft and low density materials, such as foam, are excellent during absorbing sound and can therefore be used to neutralise hi-frequency sounds. Sounds of different frequencies can be tackled more effectively also by deflection or absorption and these characteristics need to be thought to be when designing the acoustic isolation.
