Titel / Title:	Sound Phase Change over Barriers
Översatt titel / Translated title:	Fasbyte av Ljud över Barriärer
Abstrakt Abstract:	Noise Barriers are used for cancellation of sound from roads. Sound of different frequencies travel differently over the top of the barriers. Design of barriers differ. Sound phase change can play an important role in noise cancellation. The aim of this thesis is to simulate the source, noise barrier, receiver environment by software and investigate the sound phase change for different designs of the top of noise barriers. Linear Acoustics and Wave Theory is used for wave propagation.
Populärvetenskaplig beskrivning / Popular science summary:	Avsikten med examensarbeten är att simulera en ljudkälla, bullerbarriär, lur miljö i dator och utforska fasbyte av ljud för olika former av överdel av bullerbarriärer.
