Solution Overview

Problem

Binaural hearing systems face challenges in providing an optimal hearing experience due to differences in sound signals and hearing losses between the left and right ears, leading to impractical modifications and affecting interference noise elimination and directional microphony.

Innovation Solution

A method that uses a perceptive model for binaural hearing to determine unique setting values for each device, allowing for improved binaural perception by automatically controlling the hearing system, including the activation or deactivation of noise elimination and directional microphone functions based on psychoacoustic variables.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If different parameters are used for left and right devices to accommodate individual hearing losses and signal differences, then individual hearing requirements are met, but binaural symmetry and hearing impression consistency deteriorate

Engineering Contradiction:
Improveindividual hearing requirementsVSAvoidbinaural symmetry
Core Design Contradiction:
Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The patent applies local quality by allowing different parameter settings for the left and right hearing devices to accommodate individual hearing losses and signal characteristics of each ear, while simultaneously using a perceptive model to ensure overall binaural symmetry and consistent hearing impression across both devices

Inventive Principle:
Principle #3Local quality

2Reliability

If algorithms like interference noise elimination and directional microphony are modified binaurally, then individual ear performance is optimized, but hearing impression consistency and user acceptance deteriorate

Engineering Contradiction:
Improvenoise elimination performanceVSAvoidhearing impression consistency
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent employs feedback by using a perceptive model that continuously monitors and evaluates the hearing impression from both devices, adjusting the parameters of interference noise elimination and directional microphony algorithms to maintain binaural symmetry and consistency while preserving individual ear optimization

Inventive Principle:
Principle #23Feedback

AI summary

A hearing system is provided that includes a left device that supplies an electrical sound signal for supplying the left ear of the user, and a right device that supplies an electrical sound signal for supplying the right ear of the user. A perceptive model for binaural hearing is implemented at least in one of the two devices or a further device belonging to the hearing system, with which a left setting value for the left device and/or a right setting value for the right device can be determined on the basis of the two sound signals. The left device can then be set with the left setting value and/or the right device with the right setting value. The entire process of the binaural hearing and not only the monaural hearing is thus taken into consideration for the setting of the hearing system.
