Abstract:

This paper describes how increasing emphasis is being placed on the sound quality of noise sources, for example fans. In previous studies, numerical techniques were developed for predicting noise from small cooling fans. A comparison with experiments showed good agreement for the tonal components, but not all the noise generation mechanisms could be predicted. This paper outlines an experimental scheme that was used to analyze and quantify the flow field around fans and the interaction with obstructions. The experimental setup also allows to measure and quantify acoustic emissions and to evaluate the psychoacoustic characteristics of recorded sounds. The setup is used to develop quiet fan solutions that maximize performance while improving the end user experience.
