Low Latency Audio Processing System Having Active Noise Cancellation for Ear-Worn Hearing Device - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240339099 titled 'Low Latency Audio Processing System Having Active Noise Cancellation for Ear-Worn Hearing Device
Simplified Explanation: The patent application describes an ear-worn hearing device with integrated microphones and a digital signal processing chain for active noise cancellation and speaker performance enhancement.
- The hearing device includes a speaker in a housing worn over, on, or partially in the user's ear canal.
- Microphones are built into the housing to capture sound.
- A digital signal processing chain processes audio signals between the microphones and the speaker.
- The chain includes active noise cancellation circuitry to generate anti-noise signals.
- Speaker-performance-enhancement circuitry uses the anti-noise signals to improve speaker performance without changing the audio signal format.
Potential Applications: 1. Hearing aids with advanced noise cancellation capabilities. 2. Headphones for immersive audio experiences in noisy environments. 3. Communication devices for clear voice transmission in loud settings.
Problems Solved: 1. Background noise interference in hearing devices. 2. Distorted audio quality in loud environments. 3. Limited speaker performance in noisy conditions.
Benefits: 1. Improved hearing device functionality in noisy environments. 2. Enhanced audio quality for users in challenging listening situations. 3. Clearer communication in loud settings for better user experience.
Commercial Applications: The technology can be applied in the development of high-end hearing aids, premium headphones, and communication devices for professionals working in noisy environments.
Questions about Ear-Worn Hearing Device Technology: 1. How does the active noise cancellation circuitry work in the hearing device? 2. What are the potential market opportunities for this innovative technology in the audio industry?
Original Abstract Submitted
an ear-worn hearing device includes a speaker disposed in a housing comprising a portion configured for wear over, on, or at least partially in a canal of a user's ear. microphones are integrated with the housing, and a digital signal processing chain is coupled to and located between the microphones and the speaker. the digital signal processing chain includes active noise cancellation (anc) circuitry configured to generate an anti-noise signal, and speaker-performance-enhancement circuitry coupled to the anc circuitry and configured to generate a signal based on the anti-noise signal for the speaker. the digital signal processing chain is configured to communicate audio signals between the anc circuitry and the speaker-performance-enhancement circuitry without changing a format of the audio signals.
