Airborne
Airborne sound
It is that noise generated by the disturbance of the air that surrounds sound sources and is transmitted to other spaces.
The origine sound waves collide against other surfaces, making them vibrate thus disturbing air around them again. Air-transmitted noise may be reduced by interposing one or more partitions between the source and the receiving room, which may contain materials such as dBsonic SP or dBsonic HM to avoid spreading between rooms through a dock mass system.
Reverb
It is that noise generated by the disturbance of the air that surrounds sound sources and that is reflected on the surfaces of the room where the source is located, increasing the final power of the sound.
The geometry of the room, its volume, its surface and its decoration influence to either aggravate or minimise the problem. The places which suffer from this phenomenon can solve the problem using dBcomfort HP, Farbe or Scure to decrease the reverb and increase the conditions of acoustic comfort of the enclosure.
Structural
Impact sound
It is that noise that is generated by the blows to a surface.
This excitation of the surface can be transmitted to other spaces due to the rigidity of the building structures in a direct or indirect way. Indirect transmission is produced through structures adjacent to a main separation element, as can be a common wall between two precincts (this phenomenon is known as flanking). The most effective solution is coupling of elastic elements like dBimpact SP, dBimpact ZC
Vibrations
It is that noise generated by the cyclic movement of a mechanical element, such as an engine, a pump or an air conditioner.
It is transmitted through solid joints and can affect spaces far away from the source if it is connected to the structure. To avoid the transmission of vibrations, it has to be disconnected through the collation of elastic elements. To do this, it is necessary to use technical solutions with very resistant materials which work in the appropriate range of loads, such as dBbalance.
