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, determine an OE gain profile based on this information, and adjust it based on data from the voice accelerometer.
- The processors then generate an OE cancellation signal to equalize the OE profile, receive audio content from the feedforward and feedback microphones, and adjust the audio output based on the cancellation signal and the received audio content.
Key Features and Innovation:
- Wearable device with feedforward and feedback microphones
- Voice accelerometer for data collection
- Processors for adjusting audio output based on occlusion effect profiles
Potential Applications:
- Hearing aid technology
- Noise cancellation devices
- Communication devices for individuals with hearing impairments
Problems Solved:
- Addressing occlusion effect in ear canal
- Improving audio quality in wearable devices
Benefits:
- Enhanced sound quality
- Improved user experience for individuals with hearing issues
- Better noise cancellation capabilities
Commercial Applications:
- "Enhanced Audio Wearable Device for Improved Sound Quality and Noise Cancellation"
Prior Art: Prior research on occlusion effect cancellation in audio devices
Frequently Updated Research: Ongoing studies on improving sound quality in wearable technology
Questions about the Technology: 1. How does the voice accelerometer data contribute to adjusting the audio output? 2. What are the potential implications of this technology for individuals with hearing impairments?
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.
