Description
Summary:This report describes a thesis work performed at Luleå University of Technology in collaboration with Icemakers AB in Arjeplog. The goal of the thesis was to investigate if rattle in the vehicle compartment could be quantified with psychoacoustic parameters. Sound has been recorded in the vehicle compartment with an artificial head and analysis of the recordings has been performed in the program ArtemiS. Analysis showed that the psychoacoustic parameter Roughness best describes the rattle in the vehicle compartment produced under these conditions Validerat; 20101217 (root)
