Publication number: 20240331677Abstract: 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.Type: ApplicationFiled: March 27, 2023Publication date: October 3, 2024Inventors: Nils Thomas Fritiof Lunner, Morteza Khaleghimeybodi, Buye Xu, Sang-Ik Terry Cho, Sebastian Elliot Chafe, Muhammad Zubair Ikram

Patent number: 12039991Abstract: An artificial reality headset enhances audio signals from a target sound source using information from other devices in the local area. A primary headset broadcasts a location of a target sound source to secondary headsets in a local area. The secondary headsets transmit audio signals to the primary headset to enhance the audio content presented by the primary headset to a user. The secondary headset may select an array transfer function for the location of the target sound source. The secondary headsets correlate known transfer functions in the target direction with estimated transfer functions. The secondary headset may perform beamforming on the target sound source and transmit the output audio signal to the primary headset. In some embodiments, the secondary headset may transmit the array transfer function and a raw audio signal to the primary headset. The primary headset generates audio content based on the received audio signal.Type: GrantFiled: November 22, 2021Date of Patent: July 16, 2024Assignee: META PLATFORMS TECHNOLOGIES, LLCInventors: Vinay Kumar Kothapally, Jacob Ryan Donley, Buye Xu
