Abstract
This report deals with a specific case of acoustic problems; a property in Lund whose main use as a concert venue is disturbed by traffic noise while at the same time room acoustic measures are needed. Health effects and sound transmission is examined Before the proposed actions are discussed. Transmission through walls, windows and air intakes are examined both individually and as a composite construction. A computer
model in CATT Acoustics is used to predict the room acoustics in the concert hall. Absorbers and Helmholtz resonators are discussed as a solution to high reverberation.
Abstract (Swedish)
Denna rapport tar upp ett specifikt fall av akustiska problem; en fastighet i Lund vars huvudsakliga användningsområde som konsertlokal störs av trafikbuller samtidigt som rumsakustiska åtgärder behövs. Hälsoeffekter och ljudtransmission undersöks innan åtgärdsförslag diskuteras. Transmission genom vägg, fönster och tilluftsdon avhandlas
såväl individuellt och som en sammansätt konstruktion. En beräkningsmodell i CATTacoustics används för att förutspå rumsakustiken i konsertsalen. Absorbenter och Helmholtzresonatorer diskuteras som lösning på hög efterklangstid.
