Method for directional location and locating system
View Patent ↗In order to locate electromagnetic or acoustic signal sources of a sensor configuration ( 1 a through 1 c ) fitted with at least two electric outputs; where the incidence-dependent transfer functions between the acoustic signals incident on the input(s) of the sensor configuration ( 1 a through 1 c ) and the electric output signals are different, the ratio ( 7 X through 7 XX ) of the output signal is formed and the result then is correlated with the previously determined ratio function ( 11 ).
1. A method for controlling the directional characteristic of a hearing device comprising the steps of:
detecting directional orientation of distinct acoustical sources with respect to the hearing aid;
analyzing in dependency of said directional orientation said sources to obtain a function depending on a statistical distribution of a characteristic of said sources and introducing an increased attenuation for acoustical signals received from a source which satisfies a criterion according to said function.
2. A method for controlling the transfer characteristic between acoustical signals impinging upon a hearing device and mechanical signals transmitted to an individual's ear comprising the steps of:
detecting directional orientation of distinct acoustical sources with respect to the hearing aid;
analyzing in dependency of said directional orientation said sources to obtain a function depending on a statistical distribution of a characteristic of said sources and introducing an increased attenuation for acoustical signals received from a source which satisfies a criterion according to said function.
3. A method for controlling the transfer characteristic between acoustical signals impinging upon a hearing device and mechanical signals transmitted to an individual's ear comprising the steps of:
detecting directional orientation of distinct acoustical sources with respect to the hearing aid, forming a histogram of said directional orientations of said sources and introducing an increased attenuation for acoustical signals received from a source which satisfies a predetermined criterion with respect to directional orientation in said histogram.
4. A method for controlling the transfer characteristic between acoustical signals impinging upon a hearing device and mechanical signals transmitted to an individual's ear comprising the steps of:
detecting directional orientations of distinct acoustical sources with respect to the hearing device;
analyzing said directional orientations of said sources to obtain a function depending on a statistical frequency distribution of said directional orientations; and
introducing an adjusted transfer characteristic for acoustical signals received from a source which satisfies a criterion according to said function.
