Applications of sound intensity and sound power for identification of noise sources

G. Lemire, J. Nicolas


Sound intensity and sound power provide useful information to identify and rank noise sources, and to guide the noise control engineer toward an effective solution. This paper describes a case study where solutions proposed without the knowledge of sound power have proven to be ineffective. It is shown how this result could have been predicted by sound intensity and power measurements and how they can point out the sources that should have been treated.
