Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sound reinforcement systems for individuals with mobile hearing aids in public settings, such as meetings, fail to balance user-friendliness with protection of personal privacy and efficient communication.
Innovation Solution
A method utilizing an audiovisual system with a computer, screen, and microphone to receive and transmit data from mobile hearing aids, including image recognition and wireless voice transmission, ensuring secure and private communication by using identifiers and encryption, and optionally incorporating face and voice recognition for automatic activation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If public addressing systems transmit sound to all hearing aids in range, then all persons receive the communication, but privacy is compromised and unintended persons receive the audio signal
Solution Approach 1:
The patent introduces an intermediary selection mechanism where the speaker first selects the intended recipient through image selection on a display device before audio transmission occurs. This intermediary step acts as a gatekeeper, ensuring that only authorized recipients receive the audio signal while maintaining privacy protection.
Solution Approach 2:
The system performs preliminary identification and selection actions before the actual audio transmission. The speaker selects the intended recipient's image from displayed options, and the system prepares the targeted transmission parameters in advance, ensuring privacy is maintained by establishing the recipient identity before sound is transmitted.
2Ease of operation
If the system displays images of all persons for selection, then the speaker can identify the intended recipient, but the complexity of the system increases
Solution Approach 1:
The patent uses image copies or representations of persons displayed on a screen rather than requiring direct interaction with the persons themselves. These visual copies serve as selectable interfaces, allowing the speaker to identify and select the intended recipient through a simplified graphical interface without increasing physical system complexity.
Solution Approach 2:
The display device acts as an intermediary interface between the speaker and the hearing aid users. By presenting visual images of persons on the display, the system mediates the selection process in a user-friendly manner while keeping the underlying technical complexity contained within the system infrastructure.
3Object-affected harmful factors
If the system uses encrypted transmission with access codes, then privacy is protected, but the ease of operation decreases
Solution Approach 1:
The system automatically manages the encryption and decryption processes without requiring users to manually input access codes or configure security settings. The hearing aids and broadcast system handle the cryptographic operations self-service style, maintaining privacy protection while keeping the user interface simple and intuitive.
Solution Approach 2:
The system introduces an automated intermediary process that handles the complex encryption and decryption operations. Instead of requiring users to directly manage security codes, the system mediates these cryptographic operations in the background, preserving privacy while maintaining ease of operation at the user interface level.

AI summary
The invention relates to a method for providing sound to persons (10, 20, 30) by means of mobile hearing systems (11, 21, 31) during a talk with a speaker (1), and by means of an audiovisual system (2, 3, 4), the audiovisual system having a computer (2), a screen (3) and a microphone (4). The method comprises the following steps: receiving first data from a first mobile hearing system (11), which is worn by a first person (10), the first data referencing an image (12) of the first person (10); receiving second data from a second mobile hearing system (21), which is worn by a second person (20), the second data referencing an image (22) of the second person (20); displaying the image (12) of the first person (10) and the image (22) of the second person (20) on the screen (3) for perception by the speaker (1); selecting of a person (10, 20) by the speaker (1) by the selection of one of the displayed images (12, 22); generating a speech signal by recording speech of the speaker (1) by means of the microphone (4); wirelessly transmitting the speech signal to the mobile hearing system (11, 12) of the selected person (10, 20); and presenting the speech signal by means of a loudspeaker of the mobile hearing system (11, 12) for perception by the selected person (10, 20).
