Abstract
Acoustical signals from the acoustical surrounding (U) which impinge upon a reception unit 30 are evaluated and direction of arrival (DOA) of such signals is determined. From signals indicative of such direction of arrival (DOA) a histogram is formed in unit 32. The behaviour of such histogram is classified under different aspects or criteria and dependent on classification results in a classifying unit 34 the hearing device and thereby especially its signal transfer characteristic from input acoustical signals to output mechanical signals is controlled or adjusted.
Claims55
A method for producing control signals or data at a hearing device for controlling a signal transfer characteristic of acoustical signals impinging on said device to electrical signals driving at least one electrical/mechanical output converter of said device, comprising the steps of generating first signals or data which are indicative of direction of arrival of acoustical signals impinging on a sensing area of said device and generating said control signals or -data in dependency of said first signals or data.
A method of controlling signal transfer of acoustical signals impinging on a sensing area to electrical signals driving at least one electrical/mechanical output converter in a hearing device comprising the steps of generating at said device first signals or data which are indicative of direction of arrival of acoustical signals impinging on said sensing area and controlling said signal transfer by control signals or data in dependency of said first signals or data.
A hearing device with an acoustical/electrical input converter arrangement with an output, an electrical/mechanical output converter arrangement with an input, a direction of arrival determining unit with an input operationally connected to said output of said acoustical/electrical converter arrangement and generating at an output a signal or data indicative of direction of arrival of acoustical signals impinging on said acoustical/electrical input converter arrangement, a controlled signal transfer unit the input thereof being operationally connected to the output of said acoustical/electrical input converter arrangement, the output thereof being operationally connected to the input of said electrical/mechanical output converter arrangement and providing for controlled signal transfer between said input and said output and having a control input being operationally connected to the output of said direction of arrival determining unit.
A method of manufacturing a hearing device comprising
- providing at least one device casing
- providing in said casing an acoustical/electrical input converter arrangement with an output
- providing an electrical/mechanical output converter arrangement, with an input in at least one of said at least one casings
- providing a direction of arrival determining unit in at least one of said at least one casings, with an input and with an output
- providing a controlled signal transfer unit in at least one of said at least one casings with an input, an output and a control input
- and establishing following operational connections:
- between said input of said direction of arrival determining unit and said output of said input converter arrangement
- between said input of said transfer unit and said output of said input converter arrangement
- between said control input and said output of said determining unit
- between said output of said transfer unit and said input of said output converter.
