A method for operating a hearing device worn by a hearing device user. The method includes picking up an audio signal (a) by an input transducer of the hearing device. The audio signal (a) includes a source signal (s) of a sound source (SS) and a disturbing signal (d) of a disturbing source (DS). The method also includes receiving a transmission signal (d_AIS) via an interface unit of the hearing device. The transmission signal (d_AIS) includes the disturbing signal (d) or at least characteristic features of the disturbing signal (d). The method also includes at least partially eliminating the disturbing signal (d) from the audio signal (a) by using the disturbing signal (d) transmitted by the transmission signal (d_AIS) or by using the characteristic features of the disturbing signal (d) transmitted by the transmission signal (d_AIS) for obtaining an adjusted audio signal (a*), and processing the adjusted audio signal (a*).

Method for operating a hearing device as well as a hearing device

Method for operating a hearing device () that is worn by a hearing device user (), the method comprising the steps of receiving a transmission signal () comprising an audio signal () of a sound sources (S), determining a distance (d) between the sound source (S) and the hearing device (), and generating an output signal supplied to an output transducer () of the hearing device () by at least taking into account the audio signal () of the transmission signal () and the distance (d). Further embodiments are directed to determining an angle (&#x3b1;) defined by a sagittal plane () of the hearing device user () and a line drawn between the hearing device () and the sound source (S). The angle (&#x3b1;) is additionally used to generate the output signal supplied to the output transducer () of the hearing device ().

Methods for operating a hearing device as well as hearing devices

The method for operating a hearing system comprises the steps of It preferably comprises the steps of The hearing system comprises at least one decision unit adapted to deciding whether or not to execute functionalities the hearing system is requested to execute. The invention can make it possible to form hearing systems from a wide range of devices.

Hearing system and method for operating the same

The binaural hearing system comprises a first hearing device and a second hearing device, each comprising an output transducer for converting audio signals into signals to be perceived by a user of the hearing system. A communication link interconnects the first and second hearing devices. A sound generator comprised in the first hearing device generates first audio signals. The first hearing device is adapted to transmit the first audio signals to the second hearing device via the communication link. Through the transmission of the generated first audio signals, it is possible to achieve a predictable latency for the perception of the first audio signals by the user's two ears.

Synchronization of sound generated in binaural hearing system

The method of operating a hearing system comprising at least two devices comprises the step of establishing a common network time among said at least two devices. Said at least two devices can be provided with information on the number of network time units that passed since a time zero point of said common network time. Information on the common network time can be communicated from one device to another device. A wireless link can be used for establishing said common network time. The common network time not only allows for a precise synchronization of events within the hearing system, but also for ordering and sequencing events. A priorization of events, like tasks and actions, is enabled, based on the common network time. Doubly-received or obsolete commands can be recognized and deleted, and tasks can be scheduled.

Hearing system with network time

The hearing system () comprises a first processing unit (A); a second processing unit (B); and a scheduling unit () for jointly scheduling tasks to be executed in said first processing unit (A) and tasks to be executed in said second processing unit (B). Preferably, the hearing system () comprises a first device (A) comprising said first processing unit (A); and a second device (B) comprising said second processing unit (B). The method for operating a hearing system () comprising a first (A) and a second (B) processing unit, comprises the step of jointly scheduling at least one task to be executed in said first processing unit (A) and at least one task to be executed in said second processing unit (B). If, during scheduling of a task to be executed in said first processing unit, tasks to be executed in said second processing unit can be considered, an improved performance of the hearing system () can be achieved, e.g, an improved time synchronization or an improved handling of obsolete tasks.
