Sounding out timber ' s acoustic design
Rotho Blaas, which has been developing and providing solutions for the timber construction for two decades, explains the science behind noise reduction in timber structures.
By Rotho Blaas
When we speak about acoustic design of wooden buildings, we have to mention the great chance that we have: to act directly on the structure. In fact, the propagation of impact noises can be strongly reduced at the structural level by using high performing resilient soundproofing profiles. This is the most performing solution in terms of soundproofing of timber buildings in order to avoid the transmission of structural vibration.
Rotho Blaas’ s new soundproofing profile, Xylofon.
Xylofon is a new soundproofing profile of Rotho Blaas, is made by an elastic and stable polyurethane mixture that significantly reduces( from 5dB to over 15dB) the transmission of structural noise. This monolithic composition ensures stability, waterproofing and no yielding over the time in only 6mm of thickness.
This integrated design enhances Rotho Blaas to act directly at the base of the problem by working on the disconnection of all contact points along walls and floors. Timber is one of the lightest materials and therefore one of the most sensitive to acoustic vibration at low frequency.
But this dry-layered system built in sequenced phases and for elements overlapping is, at the same time, the construction technology that offers Rotho Blaas the best chance for intervention in impact noise soundproofing.
Because timber is a light material, it is highly sensitive to acoustic vibration.
