The goal of the master thesis is to improve the measuring set-up of the alternator drive in the anechoic chamber. As part of the assignment, we made several changes to the measuring table that resulted in a more massive and rigid structure. We also increased the number of microphones for alternator noise measurements from ten to twenty. Finally, we performed sound power measurements at the old and new test sites and compared the results. In conclusion, we observed how certain changes to the drive table affected the noise measurements.
