ACTIVE NOISE CANCELLATION USING REMOTE SENSING FOR OPEN-EAR HEADSET - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240331677 titled 'ACTIVE NOISE CANCELLATION USING REMOTE SENSING FOR OPEN-EAR HEADSET

Simplified Explanation: This patent application describes a device that performs active noise cancellation for a user without blocking the ear canal. It uses a sensor outside the ear to measure vibrational data indicative of sound pressure levels or pinna vibration. A prediction pipeline generates sound pressure predictions within the ear canal based on the measured data and the user's unique head and pinna shape. These predictions are used to generate audio instructions for noise cancellation using transducers.

• Sensor outside the ear measures vibrational data
• Prediction pipeline generates sound pressure predictions within the ear canal
• Audio instructions for noise cancellation are generated based on predictions
• Transducers are used for active noise cancellation
• User's unique head and pinna shape is taken into account

Potential Applications: - Consumer headphones - Hearing aids - Communication devices in noisy environments

Problems Solved: - Active noise cancellation without blocking the ear canal - Personalized noise cancellation based on individual head and pinna shape

Benefits: - Improved comfort for users - Enhanced noise cancellation performance - Customized noise cancellation experience

Commercial Applications: Title: Innovative Active Noise Cancellation Device for Personalized Sound Experience This technology can be used in consumer electronics, healthcare devices, and communication equipment to provide users with a more comfortable and effective noise cancellation experience.

Prior Art: Prior art related to this technology may include research on active noise cancellation devices, personalized audio technologies, and sensor-based sound processing systems.

Frequently Updated Research: Researchers may be exploring advancements in sensor technology, personalized audio algorithms, and transducer design for improved noise cancellation performance.

Questions about Active Noise Cancellation Technology: 1. How does this technology differ from traditional active noise cancellation devices? 2. What are the potential challenges in implementing personalized noise cancellation based on individual head and pinna shapes?

Original Abstract Submitted

an open-ear device performs active noise cancellation (anc) for a user. a sensor located outside an ear of a user which does not occlude an ear canal of the ear and measures vibrational data indicative of a sound pressure level at a location outside the ear, or a level of pinna vibration of the user. a prediction pipeline generates a prediction of sound pressure within the ear canal using an individualized model, taking into account the measured vibrational data and the unique geometric shape of the user's head and pinna. this sound pressure prediction is used to generate audio instructions for rendering playback at an noise cancellation source, such as a bone conduction transducer and/or cartilage transducer, to perform anc for the user by cancelling at least portion of the sound received at the ear canal.
