Sounding out timber ' s acoustic design

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 .
