Problems solved by technology

[0009] (2) The brain-computer interface is large in size and requires EEG caps, headbands, or hosts similar to EEG electrodes
This makes the device susceptible to electrode movement and limits the measurement accuracy of the device because the electrodes are not fixed
This also requires recalibration every time the device is removed

Embodiment Construction

[0079] Figures 1a-1d Four embodiments of hearing devices are shown. Figure 1a A simple hearing aid is shown comprising a forward or signal path from an input transducer to an output transducer, the forward path being formed therebetween and comprising a signal for applying a frequency dependent gain to the signal picked up by the microphone and boosting the Provided to the processing unit HA-DSP of the output converter. Hearing aid feedback cancellation systems (used to reduce or cancel acoustic feedback from the output of the hearing aid to the "external" feedback path (AC FB) of the input transducer) may include adaptive filters ( Figure 1b "Adaptive Filter" in ) which is controlled by a prediction error algorithm such as the LMS (Least Mean Square) algorithm to predict and cancel the portion of the microphone signal caused by feedback (from the hearing aid's receiver). Figure 1b and 1c An example thereof is shown. Adaptive filter (in Figure 1c , including a variab...

Abstract

The present disclosure relates to a communication device. The device comprises input for receiving sound signal to be processed and presented to a user, and output for outputting the processed signal to a user perceivable as sound. The processing is performed by use of a processor for processing the sound signal in dependence of a setting or a set of setting to compensate a hearing loss profile. Further, the communication device comprises a bio-signal acquisition and amplifier component in communication with a user interface for providing the biosignals as input to the user interface, the user interface controlling the setting or set of setting for operation of the communication device.

Description

technical field [0001] This application relates to the use of brain-computer interfaces to control hearing aids. The present application also relates to controlling hearing aids using an eye monitoring interface. [0002] For example, the present invention may be used in applications such as hearing aid devices, headphones, headsets, active ear protection systems, hands-free phone systems, mobile phones, teleconferencing systems, broadcasting systems, karaoke systems, classroom amplification systems, and the like. Background technique [0003] A brain-computer interface (BCI) is a communication system that helps a user interact with an external environment by converting brain signals into machine commands. The use of electroencephalograph (EEG) signals has become the most common method for BCI because of their availability and strong reliability. Many EEG-based BCI devices have been developed with conventional wet or microelectromechanical system (MEMS) type EEG sensors. ...
