Schalldämmmaß
-
Beispielsätze:
- Hohe Schalldämmmaße R bedeuten eine geringe Schallübertragung und eine gute Dämmleistung.
- Das Schalldämmmaß R ist das Verhältnis der Schallintensität der auf eine Trennschicht auftreffenden und der durchgelassenen Schallintensität.
sound insulation
Description:
Sound insulation is designed to impede or prevent the propagation of airborne and solid-borne sound by reflecting it as it crosses between two media. For example, rooms can be separated acoustically using special insulation designed to muffle footfall noise. The effect of an insulating measure, i.e. how much sound it reflects, is indicated by the dimensionless sound pressure reflection coefficient r. It is the quotient of the sound pressure of the reflected sound wave and the sound pressure of the incident sound wave. The sound Reduction index R is the ratio between the sound intensity that is measured at a partition and the sound intensity that passes through the partition. It varies according to the frequency and angle of incidence of the sound waves. High sound transmission losses R indicate low sound transmission and good insulating performance. By contrast, sound Damping and sound absorption are measures implemented in the room itself that are designed to absorb sound energy and convert it to heat energy.
