Applying New Algorithms for Numerical Integration on the Sphere in the Far Field of Sound Pressure
Acoustics, 2023 For some sound sources, the function of the square of sound pressure amplitudes on the sphere in the far field is an integrable function or can be integrated with geometrical simplifications, so an exact or approximated analytical expression for the ...
