Impact sound

Nyquist Team
The pounding of footsteps from the upstairs neighbor, a falling object, the sliding of a chair – these are the nightmares of apartment residents. The impact sound uses the building's structure as a highway to your apartment.
Professional Definition
> Impact sound – a specific form of material sound generated as a result of exciting the ceiling to vibrate during its use.
The primary assessment parameter is the standardized weighted impact sound level (L'n,w).
## Acoustics in Simple Words
Imagine the ceiling as the membrane of a large drum. When a neighbor walks on the floor, it's like hitting the drum with a stick. The impact energy goes directly into the concrete.
## Summary
Impact sound is generated through mechanical contact with the building structure. It requires solutions such as floating floors.
