Research output: Contribution to journalArticleResearchpeer-review


This paper reviews the theoretical concepts associated with three different sound power models (constant power sources, constant volume sources and constant pressure sources) and reports on some experiments that have been conducted using a custom-built portable, sound intensity measurement system to analyse the effects of bounding reflecting surfaces on the radiated sound power of a small domestic vacuum cleaner motor and a pneumatic hand drill.
