Abstract
Described is a device for creating a sound source comprising integrated measuring means (50) for measuring a property representative of the strength of the sound source, the device comprising a sound generator (40a, 40b) for generating sound within an annular space defined around a central axis, the device comprising a pair of guiding surfaces (113, 123) for guiding sound away from the annular space in opposite directions along the central axis. With sound being guided as described, sound in addition being allowed to propagate outside the device in a radial direction with respect to the central axis, a high degree of omnidirectionality of the created sound source is attained.
