Patent number: 11189301Abstract: Utterances spoken or sung by a first person can be received, in real time. The detected utterances can be compared to at least a stored sample of utterances spoken or sung by the first person. Based on the comparing, audio of the utterances spoken or sung by the first person can be isolated from a background noise. A volume of the utterances spoken or sung by a first person relative to the background noise can be determined. A key indicator that indicates the volume of the detected utterances spoken or sung by the first person relative to the background noise can be generated. Based on the key indicator, information indicating the volume of the detected utterances spoken or sung by the first person relative to the background noise can be communicated.Type: GrantFiled: July 16, 2019Date of Patent: November 30, 2021Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Alan D. Emery, Aditya Sood, Mathews Thomas, Janki Y. Vora

Patent number: 11184708Abstract: A wearable audio output device in a physical environment includes an input device and one or more microphones. While ambient sound from the physical environment is being detected by the microphone(s), the wearable audio output device: while in a first mode, provides a first audio output including one or more pass-through audio components selected so as to increase audio pass-through of the ambient sound; detects an input via the input device; in response to detecting the input, and in accordance with a determination that the input is a first type of gesture, transitions from the first mode to a second mode; and, while in the second mode, provides a second audio output including one or more cancellation audio components selected so as to increase audio cancellation of the ambient sound.Type: GrantFiled: September 22, 2020Date of Patent: November 23, 2021Assignee: APPLE INC.Inventors: Taylor G. Carrigan, David C. Graham, Thomas S. Hulbert, Dustin A. Hatfield, Gemma A. Roper, Karlin Y. Bark, David H. Bloom, Benjamin G. Jackson, Brenton A. Baugh, Shota Aoyagi

Patent number: 11176958Abstract: In some examples, loudness enhancement based on multiband range compression may include determining, based on variations in compression parameters that include compression thresholds and compression ratios, corresponding variations in loudness levels for a specified loudness standard. A learning model may be trained based on the variations in the compression parameters and the corresponding variations in the loudness levels. A specified loudness level for a device may be ascertained, for example, from a user of the device. The compression parameters for the specified loudness level may be determined based on the trained learning model. Further, sub-band compression of an input audio signal may be performed, based on the determined compression parameters, by processing the input audio signal using a perfect reconstruction filterbank.Type: GrantFiled: April 28, 2017Date of Patent: November 16, 2021Assignee: Hewlett-Packard Development Company, L.P.Inventor: Sunil Bharitkar

Patent number: 11171621Abstract: An audio playback device detects via an acoustic sensor of an audio playback device, ambient noise surrounding the audio playback device. The audio playback device updates an equalization filter based on the detected ambient noise, wherein the equalization filter adjusts one or more acoustic parameters of content presented by the audio playback device. The audio playback device adjusts a leakage control parameter based on the detected ambient noise, wherein the leakage control parameter adjusts an amount of leakage of content presented by the audio playback device. The audio playback device applies the equalization filter and the adjusted leakage control parameter to audio content. The audio playback device provides, via one or more acoustic speakers, the audio content to a user.Type: GrantFiled: March 4, 2020Date of Patent: November 9, 2021Assignee: Facebook Technologies, LLCInventors: Samuel Steele Noertker, Andrew Lovitt, Tetsuro Oishi
