1. 1. Accuracy verification of GT-Power model and reduction of computational time

   Master-uppsats, KTH/Marcus Wallenberg Laboratoriet MWL

   Författare :Viktor Dahl; Maja Dyrsmeds; [2022]
   Nyckelord :Vehicle acoustics; GT-Power; Exhaust system; Internal combustion engine;

   Sammanfattning : The noise produced by any new vehicles is tightly regulated by the European Union which have developed a standardised method for measuring the emitted noise of new vehicles. The method involves a vehicle driving past carefully positioned microphones at a specific range of engine speeds. LÄS MER

3. 2. Brake noise : A study in multi-tonal brake squeal

   Master-uppsats, KTH/MWL Marcus Wallenberg Laboratoriet

   Författare :Viktor Wiese; [2017]
   Nyckelord :;

   Sammanfattning : Brake squeal is a major problem for the vehicle industry due to recla-mations and quality perception of vehicles, as well as the unpredictability of its occurrence. This report investigates the physical reasons behind a multi-tonal brake squeal generated in a motorcycle disc brake. LÄS MER

4. 3. Lågfrekvent buller hos Vindkraftverk och Trafik

   Master-uppsats, KTH/MWL Marcus Wallenberg Laboratoriet

   Författare :Viktor Alborz Wetterblad Tari; [2012]
   Nyckelord :;

   Sammanfattning : This thesis deals with noise from wind turbines and low-frequency traffic noise. The aim was to gain practical experience by using different measurement techniques, where the wind noise was measured by emission, immission, ambisonic and binaural recordings. Both examined wind turbines have tonal components at 500Hz and 2000Hz. LÄS MER
