Patent number: 11403935Abstract: A communication circuit communicates with a right earphone worn on a right ear of a user and a left earphone worn on a left ear of the user to receive a first output signal generated by a first motion sensor provided in the right earphone and a second output signal generated by a second motion sensor provided in the left earphone. A detector detects whether a third party has approached the user based on a difference value between the first output signal and the second output signal received by the communication circuit. A notification unit notifies the user that the third party has approached the user when the detector detects that the third party has approached the user.Type: GrantFiled: March 16, 2021Date of Patent: August 2, 2022Assignee: JVCKENWOOD CORPORATIONInventors: Aki Hamada, Masaki Takei, Toru Kaiwa, Hiromitsu Asaka, Misa Suzuki, Masashi Uemoto, Miharu Kobayashi

Patent number: 11394356Abstract: A system configured to perform audio limiting using block-based processing to reduce acoustic distortion and/or computational cost. While sample-by-sample processing would apply a plurality of gain ramps to a single audio sample, the block-based processing applies a single gain ramp to ensure that the audio sample is below a threshold value. To perform block-based processing, an audio limiter component identifies a maximum amplitude value across all channels for a selected audio frame of an audio signal. Using the maximum amplitude value and the threshold value, the audio limiter component determines a block gain value associated with the selected audio frame and selects between attack processing, hold processing, or release processing. Using the selected processing and the block gain value, the audio limiter component determines instantaneous gain values for the audio samples within the audio frame.Type: GrantFiled: February 12, 2021Date of Patent: July 19, 2022Assignee: Amazon Technologies, Inc.Inventor: Guillermo Daniel Garcia

Patent number: 11368776Abstract: Signal energy in auditory sub-bands of an input audio signal is determined. Sound pressure level, SPL, in those sub-bands is then determined, based on the signal energy and based on sound output sensitivity of the against-the-ear audio device. In one instance, at least first and second gain lookup tables are determined based on a hearing profile of a user of the against-the-ear audio device. Sub-band gains that are to be applied to the input audio signal are determined based on the determined SPL. When the input audio signal is for example telephony the sub-band gains are computed using the first gain lookup table, and when the input audio signal is for example media the sub-band gains are computed using the second gain lookup table. Other aspects are also described and claimed.Type: GrantFiled: May 15, 2020Date of Patent: June 21, 2022Assignee: APPLE INC.Inventors: John Woodruff, Jing Xia, Yacine Azmi

Patent number: 11315541Abstract: The disclosed computer-implemented method may include applying, via a sound reproduction system, sound cancellation that reduces an amplitude of various sound signals. The method further includes identifying, among the sound signals, an external sound whose amplitude is to be reduced by the sound cancellation. The method then includes analyzing the identified external sound to determine whether the identified external sound is to be made audible to a user and, upon determining that the external sound is to be made audible to the user, the method includes modifying the sound cancellation so that the identified external sound is made audible to the user. Various other methods, systems, and computer-readable media are also disclosed.Type: GrantFiled: April 29, 2020Date of Patent: April 26, 2022Assignee: Facebook Technologies, LLCInventors: Andrew Lovitt, Antonio John Miller, Philip Robinson, Scott Selfon
