碩士 === 國立清華大學 === 動力機械學系 === 84 === Lately, many reports attach importance to reduce the noise
radiated by working machine. From the view point of noise re-
duction, it is necessary to locate the source position and
know how much power does it radiated. The intensity method,
although, has its reliability, for a noise system which can''t
isolate any source, the method is failed to identify the source
power. In this work, a more convenient, time saving method was
investigated to identify every source power of a noise system.
The most important feature of this method is without using any
isolation techniques, one can still identify every source power
under its normal working condition. At last, we apply this
method to identify the source power of a jet printer, discuss
the mechanism by which the sound radiated and how to improve it.
