摘要： An audio source localization apparatus receives signals from a microphone array (101), and a reference processor (105) generates at least three reference beams with different directional properties. An estimation processor (107) which generates simultaneous direction estimates for two sound sources, comprises a circuit (401) combining signals of the at least three reference beams with a beam shape parameter reflecting a shape of an audio beamform and a beam direction parameter reflecting a direction of an audio beamform for the combined signal. A cost processor (403) generates a cost measure indicative of an energy of the combined signal and a minimization processor (405) estimates values of the beam shape parameter and the beam direction parameter which correspond to a local minimum of the cost measure. A direction processor (407) then determines simultaneous direction estimates for two sound sources from the determined parameter values. Improved direction estimation for two simultaneous sound sources may be achieved.

摘要： The invention relates to a method for separating a collection of ships and to a group of ships, in particularly a group of military ships. Said group of ships comprises at least two watercrafts (301, 303) and the watercrafts emit underwater sound waves. Said method also enables individual ships to be detected.

摘要： Invention provides a system and method for separating sound from an object of interest from its background and condition monitoring system and mobile phone using the same. The sound separating system includes a sound source localizing part, including at least one microphone and a processing unit, and an object direction reference determination part, determining, as object direction reference, information on directions of the object of interest with respect to the sound source localizing part; wherein the processing unit obtains information on a direction from which sound arrives at the sound source localizing part from the sound source by using microphone signal, and comparing it with the object direction reference so as to filter the sound from the background of the sound source. By having the sound separating system, it can extract the background noise from a specific device respective location and analyse only these signals from the object of interest.

摘要： The invention relates to an apparatus and a method for increasing the direction-finding accuracy of a receiver arrangement. To this end, sound waves (15) are received using the receiver arrangement (12) and the sound waves (15) are used to ascertain received signals (16a to 16c). The received signals (16a to 16c) are used to ascertain direction signal (20a to 20c) for one relative reception direction (21a to 21c) at a time, and each direction signal (20a to 20c) is used to ascertain frequency lines (64a to 64j), associated with the same reception direction (21a to 21c), for one frequency at a time in a frequency range (62) with an amplitude value (68). In addition, a respective direction function (78) is formed for each frequency in the frequency range (62), with each adjacent first function argument (80) of a direction function (78) corresponding to one of the adjacent reception directions (21a to 21c), and each first function argument (80) having, as function value (84), the amplitude value (68) or a value that has been derived from the amplitude value (68) for the frequency line (64a to 64j) of the frequency of the respective direction function (78) of the reception direction (21a to 21c) which corresponds to the first function argument (80). Each of the direction functions (78) is transformed to the spectral domain, as a result of which a first spectral function (46) is obtained which has first spectral function arguments (102). The first spectral function (46) is filled with further spectral function arguments (108) between intermediate spectral function arguments (104) from the first spectral function arguments (102), wherein the further spectral function arguments (108) each have a function value (84) of zero or in the region of zero. The filled first spectral function (46) is then transformed back from the spectral domain, as a result of which an interpolated first direction function (60) is obtained.
