Sound insulation of separation wall with wooden frame  (English)
Abstract [sv]

Arbetet inleds med grunläggande teori för byggnadsakustik. En litteraturstudie genomförs för att ta fram förbättringsalternativ för ett antal konstruktionsdelar för två valda mätobjekt. Efter utförd fältmätning beräknas sammansatt reduktionstal av skiljevägg utifrån uppmätta och utgivna värden. En jämförelse görs och förbättringsalternativen fastställs. Analys av resultat visar dels att odämpade luftdon gör stor negativ verkan på ljudreduktionen för den sammansatta fasadväggen. För lägenhetsavskiljande vägg visar sig resonans uppkomma vid ”fel” uppbyggnad av väggkonstruktionen. 

Abstract [en]

The thesis begins with basic theory of building acoustics. A literature study is made to develop improvement options for a number of building components of the two selected measurement objects. After completion of field measurement, a composite reduction index is calculated for measured and published values. A comparison is made and improvement options are set. Analysis of the results shows that undamped air-vents makes a big negative impact on the noise reduction of the composite facade wall. For apartment separation wall it turns out that resonance occur with a "wrong" wall construction.
