    Abstract: A hearing system includes a hearing aid (10) and personal communication device (20) connected via a short range data communication link. The hearing aid has a signal processor (13) processing an audio signal according to audio processing parameters, a sub-system applying respective sets of processing parameters for at least two modes, a classifier component (51) statistically analyzing the environment by comparing specific characteristics of an electrical input signal to one or more thresholds. A program selector component (16) selects automatically an appropriate mode for the signal processing sub-system according to the classifier output. The personal communication device offers the user an interface for controlling and interacting with the program selector component of the hearing aid, and for generating and transmitting a notification to the hearing aid. Upon reception of the notification, the processor adjusts at least one of the one or more thresholds used by the classifier component.

    Abstract: A mobile communication device (50) receives an audio stream as input and delivers a processed audio stream as output. The mobile communication device has a data connection providing access to the Internet, and a short range data connection for delivering a processed audio stream as output to a specific hearing aid (10). The mobile communication device acquires a data set containing hearing aid settings for the specific hearing aid from a remote server (71), and adjusts the emulation software application by means of the data set containing hearing aid settings for the specific hearing aid (10). The mobile communication device transmits the control signals and a processed audio stream to the specific hearing aid via the short range data connection and the specific hearing aid outputs the audio signal to the user without additional amplification. The invention also provides a method of signal processing in a mobile communication device.

    Abstract: A personal wearable EEG monitor (1) is adapted to be carried at the head of a person. The EEG monitor comprises an EEG sensor part having skin surface electrodes (3) for measuring EEG signals from said person. The EEG monitor comprises an EEG signal analyzer (5, 5′) adapted for monitoring and analyzing the EEG signal. The EEG monitor (1) performs at least one of the following: providing a stimulus to the person, requesting the person to perform a stimuli creating act, or identifying a stimuli creating ambient sound. The EEG monitor comprises means for identifying an induced response from the EEG signal caused by the stimuli, and a classifier for deciding whether the skin surface electrodes receive EEG signals. The invention further provides a method of monitoring EEG signals of a person.

    Abstract: A hearing assistive system comprises a personal communication device (10) and a head-worn device (20. The personal communication device (10) has a user interface (12) being adapted for user interaction, a processor (11) controlling the user interface (12) and being adapted to run an application program, a short-range radio (13), and an output transducer (15). The head-worn device (20) has an input transducer (24) adapted for converting sound into an electric signal applied to a processor (21) outputting a modified audio signal via an output transducer (25). The application program being adapted to generate and output a data packet (70) on an audio carrier via the output transducer (15). The head-worn device (20) comprises an audio signaling block (26) for detecting and decoding the data packet (70) received by the input transducer (24). The head-worn device (20) comprises a controller (27) for controlling the operation of a short-range radio (28). The audio signaling block (26) is adapted to detect a radio control command included in the data packet (70), and to instruct the controller (27) to control the short-range radio (28), accordingly.

    Abstract: An input transducer (11, 12) of a hearing aid (10) converts audio from the environment into an electric input signal. A signal processor (13) amplifies and conditions the electric input signal according to a preset set of audio processing parameters, and an output transducer (14) reproduces output audio. The hearing aid (10) is connected with a personal communication device (20) via a short range radio communication link (15, 29). The personal communication device (20) identifies music included in the background noise. The personal communication device (20) retrieves a music stream based on the identified music, and streams the music stream to the hearing aid (10). The signal processor (13) of the hearing aid (10) combines the input signal from the input transducer (11, 12) and music signal in order to reduce the presence of the music included in the background noise from the audio signal delivered by the output transducer (14).
