Devices, Methods, and Systems for Reducing the Occlusion Effect - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240348969 titled 'Devices, Methods, and Systems for Reducing the Occlusion Effect
The wearable device described in the patent application includes a feedforward microphone, a feedback microphone, and a voice accelerometer, all connected to one or more processors.
- The processors are designed to receive an occlusion effect (OE) profile related to increased sound pressure levels in an ear canal.
- Based on the OE profile, the processors determine an OE gain profile.
- Voice accelerometer data is received and used to adjust the OE gain profile.
- An OE cancellation signal is generated to equalize the OE profile.
- The device receives external audio from the feedforward microphone and audio from the ear canal from the feedback microphone.
- Using the OE cancellation signal and the audio content, the device adjusts the audio output.
Potential Applications: - Hearing aid technology - Noise cancellation devices - Communication devices for individuals with hearing impairments
Problems Solved: - Addressing the occlusion effect in ear canal audio devices - Providing a more natural and clear audio experience for users
Benefits: - Improved audio quality - Enhanced user comfort - Better communication in noisy environments
Commercial Applications: Title: "Advanced Audio Equalization Wearable Technology for Enhanced Communication" This technology can be used in hearing aids, headphones, and communication devices for individuals with hearing impairments. It can also be integrated into noise-canceling headphones for a more personalized audio experience.
Questions about the technology: 1. How does the device adjust the audio output based on the occlusion effect profile? 2. What are the potential implications of this technology for the hearing aid industry?
Original Abstract Submitted
a wearable device includes a feedforward microphone; a feedback microphone; a voice accelerometer; and one or more processors in communication with the feedforward microphone, the feedback microphone, and the voice accelerometer. the one or more processors may be configured to receive an occlusion effect (“oe”) profile associated with increased sound pressure level within an ear canal; determine an oe gain profile based on the oe profile; receive voice accelerometer data; adjust the oe gain profile based on the voice accelerometer data; generate an oe cancellation signal based on the oe gain profile to equalize the oe profile; receive, from the feedforward microphone, first audio content including external audio; receive, from the feedback microphone, second audio content including audio within the ear canal of a user; and adjust, based on the oe cancellation signal and the received first and second audio content, an audio output.
