Abstract EN
The paper presents an active sound intensity probe that can be used for sound source localization in standing wave fields.
The probe consists of a sound hard tube that is terminated by a loudspeaker and an integrated pair of microphones.
The microphones are used to decompose the standing wave field inside the tube into its incident and reflected part.
The latter is cancelled by an adaptive controller that calculates proper driving signals for the loudspeaker.
If the open end of the actively controlled tube is placed close to a vibrating surface, the radiated sound intensity can be determined by measuring the cross spectral density between the two microphones.
A one-dimensional free field can be realized effectively, as first experiments performed on a simplified test bed have shown.
Further tests proved that a prototype of the novel sound intensity probe can be calibrated.
