A geometric acoustics approach to the study of sound propagation in ducts containing sheared flows
(Acoustical Society of America, 1979-12-01)
Geometric acoustics has been used to study the propagation of sound waves in a homogeneous moving medium with sheared flow bounded by the hard walls of a duct. Differential equations describing the ray trajectories and the ...
Prediction of sound pressure levels in irregularly shaped factory spaces
(Acoustical Society of America, 1976)
The prediction of sound pressure levels in irregularly shaped factory spaces is approached through an analysis of acoustically coupled rooms. Previous work has indicated that room surface sound absorption characteristics ...
Prediction of the sound diffracted around barriers in large rooms using an extension of Maekawa's approach
(Acoustical Society of America, 1977)
A computer program has been developed for the prediction of sound pressure levels in large, irregular rooms utilizing a geometric acoustics approach. Experiments indicated that the program gave good predictive accuracy ...
