Airborne noise isolation is the technique used to prevent sound from passing from one environment to another, through the use of different materials: dense, heavy, among others, that can dampen and dissipate sound energy (metal sheets, glass, wood solid, solid brick wall, rubber blankets, cork, carpets, Drywall, etc.). Isolation, as the name suggests, aims to prevent the passage/exit of sounds between different environments, between buildings and the environment.

Another factor that influences isolation is the fact of not just using a barrier, but creating a sequence of obstacles so that sound has more difficulty propagating. The use of double walls, Drywall, double-glazed windows or the combination of materials of different densities (wooden door with steel sheet) are very important to have good acoustic insulation.

In this case, it is also important to ensure that the different elements used do not touch each other directly, always using drywall, high-density acoustic blankets and whatever else is convenient to eliminate vibration.

Due to the way the sound propagates, be careful not to leave any type of gap between the closures, as this could harm the entire assembly. Doors and frames must receive special attention, with the use of blankets and rubber to ensure the environment is watertight.
