| Descripción: |
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. La mesure de 1'intensité et de la puissance acoustiques livrent des informations précieuses pour 11 identification des sources dominantes de bruit et pour l'élaboration d’une solution judicieuse et efficace au problème qu 'elles causent. Cet article décrit une étude de cas où des solutions proposées, sans avoir recours à la puissance sonore, se sont avérées inefficaces. Il est démontré comment l'intensité et la puissance acoustiques peuvent prédire les résultats obtenus et identifier les sources qui doivent être traitées. |
