Støtisolasjonsnivået

Støtisolasjonsnivået refers to the degree to which a material or building component reduces the transmission of impact sound. Impact sound, such as footsteps or dropped objects, is generated on a surface and travels through the structure to adjacent rooms or floors. A high støtisolasjonsnivå indicates that a material is effective at absorbing and dissipating this type of sound energy, thus minimizing its propagation.

This concept is particularly relevant in multi-story buildings, apartments, and offices where noise disturbance from above is a common concern. Different flooring materials and underlayments possess varying capabilities for impact sound insulation. For example, certain types of carpets with thick underpads generally offer better impact sound insulation than hard flooring like tile or wood without a dedicated underlayment.

The measurement of støtisolasjonsnivå is typically expressed in decibels (dB) using standardized testing methods. Higher dB values represent better insulation performance. Building codes and acoustic standards often specify minimum requirements for impact sound insulation to ensure acceptable living and working conditions. Selecting materials and construction methods with appropriate støtisolasjonsnivå is crucial for acoustic comfort and soundproofing design.
