What is impact Noise Transmission?

Impact Noise Transmission

Impact noise transmission occurs when noise passes through a floor into dwelling below or adjacent to the source of noise. Examples of impact noise include foot traffic, objects dropped on the floor, or banging. Impact noise is capable of travelling through solid spaces and cavities. If a room is not correctly soundproofed the volume of impact noise transmitted into other dwellings may lead to the failure of Part E Building Regulations.

Soundproofing Against Impact Noise Transmission

Impact noise is of significant concern on timber frame and steel joist developments where the constructions lack of mass makes it easier for noise to transmit from one dwelling to another. In these types of construction it is important to add mass through a high performance acoustic floor board and soundproofing wool in between the joists.

Even if a floor has been installed with acoustic treatment failure may still occur if all the required components aren’t installed. Floors must be isolated through the installation of acoustic flanking strips around the perimeter. Acoustic plasterboards and resilient bars should also be installed below timber and steel joists for maximum performance.

Concrete floors are able to cope with impact noise more effectively than timber floors due to their significant mass. These types of floors require greater attention to airborne noise when introducing soundproofing components.
