Abstract [en]

Vacuum cleaner motors work at a relatively high rpm, which produces blade passing tones at high frequencies. In this report a honeycomb-liner type silencer for vacuum cleaners has been investigated. The main purpose of the silencer is to attenuate the first order blade passing tone, at approximately 7066 Hz. No modifications have been done to the motor. With insertion loss (IL) an average attenuation of between 3-8 dB was achieved. To confirm the results sound power measurements were done, but the IL-measurement results could not be verified by them. The report includes an analytical (COMSOL Multiphysics) as well as an experimental investigation. This thesis has been done in cooperation with KTH (Marcus Wallenberg laboratory for sound and vibration research), Müller-BBM Scandinavia and Electrolux Small Appliances.
