Impact sound

Impact sound is the name given to the portion of the sound from a source that is partly propagated via solid construction components such as walls, ceiling and floor, and partly spreads through the ambient air and is re-emitted.

Floor construction and reducing impact sound
The part of the sound coming from footsteps or other mechanical impacts that enters the floor of the booth is effectively reduced by the elastic floor construction.

Depending on the purpose, Desone booths come with one of two different types of floor construction.

Measuring the impact sound level
With impact sound, too, the efficacy of an acoustic technique is determined as the difference between the levels in the source room and the receiving room – this is called the impact sound level difference. It is expressed as the weighted impact sound level L´n,w. Here a high numerical value for L´ n,w represents a large reduction of the impact sound level.

All measurements are conducted in accordance with the legally required standards by sworn independent experts.
