HEARING DEVICE WITH MOTION SENSOR USED TO DETECT FEEDBACK PATH INSTABILITY - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240298121 titled 'HEARING DEVICE WITH MOTION SENSOR USED TO DETECT FEEDBACK PATH INSTABILITY
Simplified Explanation: The patent application describes a system in an ear-wearable device that cancels feedback in an audio input signal using an adaptive feedback canceller. The system also includes a motion detector to detect motion of the device and adjust the adaptive filter accordingly.
- The system digitizes audio input signals in an ear-wearable device.
- An adaptive feedback canceller with an adaptive filter cancels feedback in the audio input signal.
- A motion detector provides a motion signal indicating device motion.
- A processor adjusts the adaptive filter based on the motion signal, making it adapt faster or slower depending on the change in feedback path.
Potential Applications: 1. Hearing aids with improved feedback cancellation. 2. Audio devices for musicians or performers. 3. Communication devices for noisy environments.
Problems Solved: 1. Feedback interference in audio input signals. 2. Inaccurate audio output due to motion of the device.
Benefits: 1. Improved audio quality. 2. Enhanced user experience in noisy environments. 3. Better performance of ear-wearable devices.
Commercial Applications: "Adaptive Feedback Canceller for Ear-Wearable Devices: Enhancing Audio Quality in Noisy Environments"
Prior Art: Prior art related to this technology may include research on adaptive feedback cancellation in audio devices and motion detection in wearable technology.
Frequently Updated Research: Researchers may be exploring advancements in adaptive feedback cancellation algorithms and motion detection technology for ear-wearable devices.
Questions about Ear-Wearable Devices: 1. How does the adaptive feedback canceller improve audio quality in ear-wearable devices? 2. What are the potential commercial applications of this technology in the audio industry?
Original Abstract Submitted
an audio input signal is digitized via circuitry of an ear-wearable device. an adaptive feedback canceller has an adaptive filter producing an output that is inserted into the digitized audio input signal to cancel feedback. a motion detector provides a motion signal indicative of motion of the car-wearable device. a processor is operable to determine a change in a feedback path based on the motion signal. the processor causes the adaptive filter to have faster adaption in response to the change in the feedback path is above a first threshold. the processor also causes the adaptive filter to have slower adaption in response to the change in the feedback path being below a second threshold.
