Publication number: 20240071404Abstract: A wind noise reduction system including a beamformer, a comparator, and a voice mixer is provided. The beamformer may be an MVDR beamformer, and generates a beamformed signal based on a first microphone signal and a second microphone signal. The comparator generates a comparison signal based on the beamformed signal and a wind microphone signal. The comparison signal may be further based on a beamformed energy level of the beamformed signal and a wind energy level of the wind microphone signal. The voice mixer generates an output voice signal based on the beamformed signal, the wind microphone signal, and the comparison signal. The wind noise reduction system may further include a wind microphone corresponding to the wind microphone signal. The wind microphone may be arranged on a portion of a wearable audio device configured to be seated in a concha of a wearer.Type: ApplicationFiled: August 30, 2022Publication date: February 29, 2024Applicant: Bose CorporationInventors: Douglas George Morton, Olivia Montana Canavan, Yang Liu

Publication number: 20240055011Abstract: A voice capture system including a first and second voice beamformer, a voice mixer, a voice rejected noise beamformer, a noise beamformer adjustor, a jammer suppressor, and a speech enhancer is provided. The first and second voice beamformer and the voice mixer generate a voice enhanced reference signal based on a first and second frequency domain microphone signal. The voice rejected noise beamformer includes filter weights and generates a noise reference signal based on the first and second frequency domain microphone signal. The noise beamformer adjustor adjusts the one or more filter weights of the voice rejected noise beamformer to account for fit variation. The jammer suppressor generates a jammer suppressed signal based on the voice enhanced reference signal and the noise reference signal. The speech enhancer dynamically generates an output voice signal by applying a dynamic noise suppression signal to each frequency bin of the jammer suppressed signal.Type: ApplicationFiled: August 11, 2022Publication date: February 15, 2024Applicant: Bose CorporationInventors: Yang Liu, Abinaya Subramaniam, Trevor Caldwell, Douglas George Morton

Patent number: 11688411Abstract: Audio systems, methods, and processor instructions are provided that detect voice activity of a user and provide an output voice signal. The systems, methods, and instructions receive a plurality of microphone signals and combine the plurality of microphone signals according to a first combination and a second combination. The first combination produces a primary signal having enhanced response in the direction of the user's mouth, and the second combination produces a reference signal having reduced response in the direction of the user's mouth. The primary signal and the reference signal are added and subtracted to produce a voice-enhanced signal and a voice-reduced signal, respectively. The voice-enhanced signal and the voice-reduced signal are compares and an output voice signal is provided based upon the comparison.Type: GrantFiled: October 24, 2022Date of Patent: June 27, 2023Assignee: Bose CorporationInventors: Douglas George Morton, Pepin Torres, Xiang-Ern Sherwin Yeo

Publication number: 20230066351Abstract: A method performed by an audio output device is provided for detecting instabilities and taking mitigating actions. Specifically, an A-weighted dBA level of a raw feedback signal exceeding a threshold level trigger, at least, muting the driver. The described methods apply to detecting instabilities across a broad frequency spectrum.Type: ApplicationFiled: August 30, 2021Publication date: March 2, 2023Inventors: Douglas George MORTON, Emery M.

The first combination produces a primary signal having enhanced response in the direction of the user's mouth, and the second combination produces a reference signal having reduced response in the direction of the user's mouth. The primary signal and the reference signal are added and subtracted to produce a summation signal and a difference signal, respectively. The summation signal and the difference signal are compares and an output voice signal is provided based upon the comparison.Type: GrantFiled: August 17, 2020Date of Patent: October 25, 2022Assignee: Bose CorporationInventors: Douglas George Morton, Pepin Torres, Xiang-Ern Sherwin Yeo

Patent number: 11277689Abstract: The present disclosure generally provides an apparatus and method of controlling an audible signal generated by an audio device to improve the sound quality of the generated audible signal and/or sound quality perceived by a user. In some embodiments, the audio device is able to improve the sound quality generated by the audio device that is generating audible sound based on any type of audio signal. The processes described herein allow the audible signal processor to determine the acoustic fingerprint of the environment in which the audio device is positioned, and thus by use of the method steps disclosed herein to optimize the sound quality in one or more frequency bands of a generated audible signal in real time based on the determined acoustic fingerprint.Type: GrantFiled: July 30, 2020Date of Patent: March 15, 2022Assignee: LOGITECH EUROPE S.A.Inventors: Calhoun Ernst Zabel, Daniel Ryan Marquez, Matthew James Green, Douglas George Morton

Patent number: 10366700Abstract: Embodiments of the disclosure generally include a method and apparatus for receiving and separating unwanted external noise from an audible input received from an audible source using an audible signal processing system that contains a plurality of audible signal sensing devices that are arranged and configured to detect an audible signal that is received from any position or angle within three dimensional space. The audible signal processing system is configured to analyze the received audible signals using a first signal processing technique that is able to separate unwanted low frequency range noise from the received audible signal and a second signal processing technique that is able to separate unwanted higher frequency range noise from the received audible signal. The audible signal processing system can then combine the signals processed by the first and second signal processing techniques to form a desired audible signal that has a high signal-to-noise ratio throughout the full speech range.Type: GrantFiled: October 18, 2017Date of Patent: July 30, 2019Assignee: LOGITECH EUROPE, S.A.Inventors: Daniel Ryan Marquez, Douglas George Morton, Matthew James Green
