Components in evaluation of complex interior truck sounds
Artikel i vetenskaplig tidskrift, 2006

In order to investigate influences on assessment of interior truck sounds two experiments have been carried out with emphasis on the low frequency content. In the first experiment the participants were presented with recorded sound from the interior of a truck cabin, with different alterations of the low frequency content. In the second experiment the balance between low and high frequency content was altered for the recorded sounds. Three main dimensions important for the assessment of truck sounds were found: an Annoyance factor, a Wakefulness factor and a Quality factor. Additionally it was found that a wellsuited spectral balance could improve positive impressions of truck sound.
