Can anyone explain me the equations regarding the Directivity Pattern of a Loudspeaker so that I can work on it's beamforming.Thank You.
You need some specific knowledge rather than "an idea" because the whole thing is pretty mathematical - particularly if you want to do your own experimenting.Yes i have the idea about the phenomenon of Diffraction in waves
The room dimensions could easily have a profound effect on resonances and that could, in turn, have a huge effect on the apparent directivity of an array at different points in the room. By that, I mean that, rather than producing a simple polar directivity pattern, you would get a response in the room that would be a three dimensional standing wave pattern, which varies with frequency. This 'colouration' is guaranteed to upset any directional information that a listener could get from an array.Can anyone help to see how a resonance condition is possible in the sound produced from a loudspeaker array and would it depend on the acoustics of the room.Thank You
