摘要： Certain aspects provide methods and apparatus for recovering audio quality of voice when processing signals associated with a wearable audio output device. A method that may be performed includes receiving. by an in-ear microphone acoustically coupled to an environment inside an car canal of a user, an audio signal having a first frequency band. predicting high-frequency band information for the audio signal using a model trained using training data of known high-frequency bands associated with low-frequency bands. generating an output signal having a second frequency band based. at least in part. on the first frequency band of the audio signal and the predicted high-frequency band information for the audio signal, and outputting. by the wearable audio output device. the output signal having the second frequency band.

摘要： This disclosure describes, in part, techniques to process audio signals to lessen the impact that wind and/or other environmental noise has upon the resulting quality of audio signals output on speaker(s) of wireless earbuds or other headphones. For example, the techniques may determine a level of wind and/or other noise in an environment and may determine how best to process the signals to lessen the impact of the noise, such that one or more users that hear audio based on output of the signals hear higher-quality audio. In some instances, the techniques are able to detect levels of wind in a relatively low-power manner and as part of regular operation of the wireless earbuds or other headphones.

摘要： A wearable device includes a feedforward microphone; a feedback microphone; a voice accelerometer; and one or more processors in communication with the feedforward microphone, the feedback microphone, and the voice accelerometer. The one or more processors may be configured to receive an occlusion effect (“OE”) profile associated with increased sound pressure level within an ear canal; determine an OE gain profile based on the OE profile; receive voice accelerometer data; adjust the OE gain profile based on the voice accelerometer data; generate an OE cancellation signal based on the OE gain profile to equalize the OE profile; receive, from the feedforward microphone, first audio content including external audio; receive, from the feedback microphone, second audio content including audio within the ear canal of a user; and adjust, based on the OE cancellation signal and the received first and second audio content, an audio output.

摘要： The present invention relates to an auditory device that combines bone-conducting earbuds with integrated electroencephalography (EEG) sensors. The device utilizes bone conduction technology to transmit sound through the skull to the inner ear, allowing for clear audio perception without obstructing the ear canal. Incorporated EEG sensors are configured with spring-loaded contacts that maintain consistent skin contact to monitor brain wave activity effectively. This dual-functionality enables users to listen to audio and simultaneously track cognitive states, making the device particularly useful for applications in cognitive load monitoring and adaptive audio feedback based on the user's mental state. This innovation extends the functionality of conventional earbuds with bone-conduction mechanisms by integrating EEG technology to enhance biosensing, health monitoring, and tailored cognitive-processing feedback.

摘要： Embodiments of systems and methods for managing performance optimization of applications executed by an Information Handling System (IHS) are described. In an illustrative, non-limiting embodiment, an IHS may include computer-executable instructions to receive, by a personal audio device, a plurality of measurements associated with an audio dosage level incurred by a user over a specified period of time, and determine that a cumulative audio dosage level for the specified period of time is excessive. A first portion of the measurements obtained when the audio dosage level is generated by a first audio source and a second portion of the measurements obtained when the audio dosage level is generated by a second audio source. Additionally, the cumulative audio dosage level obtained by combining the first portion and second portion of measurements. When the cumulative audio dosage level is excessive, perform one or more remedial actions to reduce the audio dosage level.

摘要： An in-ear headphone device for insertion in an ear canal of a person. The in-ear headphone device comprises a noise microphone, a loudspeaker and a signal processor arranged to provide an active noise control signal on the basis of a recorded audio signal from said noise microphone, wherein said loudspeaker is arranged to reproduce said active noise control signal in said ear canal. Further, the device comprises a damped vent comprising one or more vent elements and one or more dampening elements, said damped vent being arranged to couple said ear canal to an external acoustic environment. The damped vent is characterized by an inward vent transfer function HVI from said external acoustic environment to said ear canal. The damped vent is arranged to dampen an acoustic resonance of said one or more vent elements such that a resonance magnitude of said inward vent transfer function HVI of said damped vent in a resonance frequency range from 100 Hz to 2 kHz is maximally 3 dB greater than a reference magnitude of said inward vent transfer function HVI in a reference frequency range from 20 Hz to 100 Hz.
