In Situ Directivity Measurement of Flush-Mounted Loudspeakers in a Non-Environment Listening Room
Directivity is one important parameter to define the behaviour of a loudspeaker. There are many techniques and standards about directivity measurements in anechoic chambers but in situ measurements of flush-mounted loudspeakers show some specific problems. This contribution develops a procedure to measure directivity under the special conditions of a non-environment listening room, introducing the techniques utilized, the problems found with the proposed solutions and discussing the limitations of the process. The existence of reflections, baffling effects due to adjacent walls and a comparison to theoretical models of the radiation of a piston are discussed.
