Additional information
Significance of output:
This paper provides analytical formulas for estimating the sound power radiating from a duct within a uniform flow. Using these formulas, the sound power can be estimated using only a single measurement, as opposed to the numerous measurements covering a sphere surrounding the duct that would be normally required. Although similar formulas were available for the no-flow case, this paper provides formulas applicable to a duct in a uniform flow for the first time. The method outlined in this paper can easily be generalized to allow for a diffirent flow speed inside and outside of the duct.
