Problems solved by technology

[0011] The disadvantage is that the SR model corresponds to an anti-causal model, and the disadvantage is the lack of knowledge of dynamic effects and difficulties in real-time implementation, so that in practice there may be no benefit from SR

Embodiment Construction

[0176] The detailed description provided below in conjunction with the drawings serves as a description of a variety of different configurations. The detailed description includes specific details to provide a thorough understanding of a number of different concepts. However, it is obvious to those skilled in the art that these concepts can be implemented without these specific details. Several aspects of the apparatus and method are described by a number of different blocks, functional units, modules, elements, circuits, steps, processes, algorithms, etc. (collectively referred to as "elements"). Depending on specific applications, design limitations, or other reasons, these elements can be implemented using electronic hardware, computer programs, or any combination thereof.

[0177] Electronic hardware can include microprocessors, microcontrollers, digital signal processors (DSP), field programmable gate arrays (FPGA), programmable logic devices (PLD), strobe logic, discrete h...

Abstract

A hearing assistance system comprises an input unit for providing electric input sound signals u i , each representing sound signals U; from a multitude n u of sound sources S i , an electroencephalography (EEG) system for recording activity of the auditory system of the user's brain and providing a multitude ny of EEG signals yj , and a source selection processing unit receiving said electric input sound signals ui and said EEG signals yj , and in dependence thereof configured to provide a source selection signal Sx indicative of the sound source Sx that the user currently pays attention to using a selective algorithm that determines a sparse model to select the most relevant EEG electrodes and time intervals based on minimizing a cost function measuring the correlation between the individual sound sources and the EEG signals, and to determine the source selection signal Sx based on the cost functions obtained for said multitude of sound sources.

Description

Technical field [0001] This application relates to the field of hearing aid systems including devices such as hearing aids. This application particularly relates to the problem of speech representation in the human brain and the so-called cocktail party problem, that is, the separation of a single sound source and multiple sound sources of interest to the listener in a noisy and crowded background. Background technique [0002] The routine of the human brain to solve the cocktail party problem hides the inherent complexity of the problem: (1) Different competing sound sources emit different sound signals at the same time; (2) These signals are then mixed; (3) The sum of these signals enters the ears (4) It is subsequently decoupled; (5) The sound signal of interest is selected; and (6) Other sound signals are ignored in the auditory system. Although the cocktail party problem has been raised for decades, the solution to the cocktail party problem seems to be in an underdeveloped...
