Patent number: 11632648Abstract: An ear-mountable listening device includes an adaptive phased array of microphones, a speaker, and electronics. The microphones are physically arranged into a ring pattern to capture sounds emanating from an environment. Each of the microphones is configured to output one of a plurality of first audio signals that is representative of the sounds captured by a respective one of the microphones. The speaker is arranged to emit audio into an ear. The electronics are coupled to the adaptive phased array and the speaker and include logic that when executed causes the ear-mountable listening device receive a user input identifying a first sound for cancelling or amplifying, steer a null or a lobe of the adaptive phased array based upon the user input, and generate a second audio signal that drives the speaker based upon a combination of one or more of the first audio signals.Type: GrantFiled: February 10, 2022Date of Patent: April 18, 2023Assignee: Iyo Inc.Inventors: Simon Carlile, Jason Rugolo, William Woods, Takahiro Unno

Publication number: 20190253811Abstract: The present invention is adapted to assist in optimizing the performance of a hearing aid by detecting conditions which result in sub-optimal performance and assisting a user or health care professional to correct those conditions. The present invention is adapted to optimize the performance of a hearing aid by generating a reference signal which, when broadcast, creates a feedback signal. The feedback signal is then measured, or its characteristics identified, to determine whether the hearing aid system is optimized and, if not, what components or characteristics are not optimized and how to optimize the hearing aid system performance or that of its components.Type: ApplicationFiled: April 26, 2019Publication date: August 15, 2019Inventors: Takahiro UNNO, Lakshman RATHNAM, Kulbir SANDHU, Bryan FLAHERTY, Morteza KHALEGHIMEYBODI

Patent number: 9666206Abstract: At least one signal is received that represents speech and noise. In response to the at least one signal, frequency bands are generated of an output channel that represents the speech while attenuating at least some of the noise from the at least one signal. Within a kth frequency band of the at least one signal: a first ratio is determined of a clean version of the speech for a preceding time frame to the noise for the preceding time frame; and a second ratio is determined of a noisy version of the speech for the time frame n to the noise for the time frame n. In response to the first and second ratios, a gain is determined for the kth frequency band of the output channel for the time frame n.Type: GrantFiled: August 20, 2012Date of Patent: May 30, 2017Assignee: TEXAS INSTRUMENTS INCORPORATEDInventor: Takahiro Unno

Patent number: 9137611Abstract: In response to a signal failing to exceed an estimated level of noise by more than a predetermined amount for more than a predetermined continuous duration, the estimated level of noise is adjusted according to a first time constant in response to the signal rising and a second time constant in response to the signal falling, so that the estimated level of noise falls more quickly than it rises. In response to the signal exceeding the estimated level of noise by more than the predetermined amount for more than the predetermined continuous duration, a speed of adjusting the estimated level of noise is accelerated.Type: GrantFiled: August 24, 2012Date of Patent: September 15, 2015Assignee: TEXAS INSTRUMENTS INCORPORATIONInventors: Takahiro Unno, Nitish Krishna Murthy

Patent number: 8880394Abstract: In response to a first envelope within a kth frequency band of a first channel, a speech level within the kth frequency band of the first channel is estimated. In response to a second envelope within the kth frequency band of a second channel, a noise level within the kth frequency band of the second channel is estimated. A noise suppression gain for a time frame n is computed in response to the estimated speech level for a preceding time frame, the estimated noise level for the preceding time frame, the estimated speech level for the time frame n, and the estimated noise level for the time frame n. An output channel is generated in response to multiplying the noise suppression gain for the time frame n and the first channel.Type: GrantFiled: August 20, 2012Date of Patent: November 4, 2014Assignee: Texas Instruments IncorporatedInventors: Devangi Nikunj Parikh, Muhammad Zubair Ikram, Takahiro Unno
