Systems and methods for communicating information related to a wearable device are disclosed. Exemplary information includes audio information.

A method operates a hearing device which performs active noise suppression for suppressing noise signals having one or more frequency components. An audiogram is provided which specifies a hearing threshold of a user of the hearing device as a function of frequency, wherein by using the audiogram it is determined which frequency components of the noise are audible to the user and which are not audible. The noise suppression is operated selectively by suppressing audible frequency components of the noise and by not suppressing inaudible frequency components of the noise. A corresponding hearing device is operated according to the method.

An active noise control device includes a control signal generating unit including a first adaptive filter configured to generate a control signal by performing a filtering process on a reference signal corresponding to noise, an identifying unit configured to identify a peak frequency in an impedance frequency characteristic of an actuator, a peak frequency storage unit configured to store an initial peak frequency of the actuator, a first determination unit configured to determine whether or not a difference between the peak frequency currently identified and the initial peak frequency is greater than or equal to a threshold value, and a control unit configured to change a characteristic of the control signal generated by the control signal generating unit when the first determination unit determines that the difference is greater than or equal to the threshold value.

Hearing management, using a portable device or integrated portable devices, can include generating during a hearing diagnostics phase an audiogram based on responses of a user to signals conveyed to the user. In response to detecting ambient noises during the hearing diagnostics phase, noise cancellation can be performed to cancel the ambient noises in conjunction with conveying the signals to the user. During a hearing enhancement phase, sounds can be captured with the portable device. The captured sounds can be enhanced in real-time during the hearing enhancement phase by amplifying select frequencies of the captured sounds using signal gain. The frequencies can be selected, and the signal gain determined based on the audiogram. The captured sounds, now enhanced, can be conveyed to the user as frequency-enhanced sounds.

A wearable device is provided and includes a plurality of speakers including a first speaker, a second speaker, and an N.sup.th speaker, a plurality of digital to analog converter (DAC)s including a first DAC connected to the first speaker, a second DAC connected to the second speaker, and an N.sup.th DAC connected to the N.sup.th speaker, an audio signal processing module including N DAC output paths configured to filter an audio signal according to each frequency band and output the audio signal, a memory; and a processor electrically connected to the plurality of DACs, the audio signal processing module, and the memory, wherein the memory includes instructions causing the processor to, when the audio signal is reproduced, analyze a frequency component included in the audio signal, activate the N DAC output paths when the frequency component included in the audio signal has a full band range, activate only a DAC output path for processing a specific frequency band among the N DAC output paths when the frequency component included in the audio signal has only the specific frequency band, and output the audio signal through a speaker connected to the activated DAC output path.

A method performed by a headset that includes a speaker and an in-ear microphone, the method includes performing a calibration on the headset to obtain a baseline measurement; using, while the headset is being worn by a user, an audio signal to drive the speaker that is arranged to project sound into a canal of a user's ear; capturing as a microphone signal, from the in-ear microphone of the headset, sound from within the canal of the user's ear; determining a parameter associated with the user's ear based at least on the captured microphone signal and the baseline measurement; and transmitting a notification related to one or more characteristics of one or more hearing elements of the user's ear based on the parameter.

An electronic device is provided. The electronic device includes a communication module, an input module, a first output module, a second output module, a first digital to analog converter (DAC) connected to the first output module, a second DAC connected to the second output module, and at least one processor, wherein the at least one processor may be configured to identify an operation mode of the electronic device, obtain an external signal through the communication module, or obtain an input signal through the input module, generate an output signal corresponding to the operation mode, and control the first DAC and the second DAC in response to the operation mode.

In certain aspects, an active noise control (ANC) method and system for a headphone are disclosed. It is determined whether a music signal is played by a speaker of the headphone. Responsive to the music signal not being played by the speaker and a noise level of an ambient noise signal being greater than a noise threshold, a set of noise feedforward (FF) signals is obtained based on a set of FF microphone signals acquired by a set of FF microphones of the headphone. A noise feedback (FB) signal is obtained based on a first FB microphone signal acquired by a FB microphone of the headphone. A set of leakage monitoring parameters is obtained based on the set of noise FF signals and the noise FB signal. A set of FF filter parameters for a set of FF filters is adjusted based on the set of leakage monitoring parameters.

Noise abatement within a signal stream containing unwanted signal referred to as noise is performed by acquiring a digitized noise signal and using a digital processor circuit to subdivide the acquired noise signal into different frequency band segments and thereby generate a plurality of segmented noise signals. Then individually for each segmented noise signal, the processor shifts in time the segmented noise signal by an amount dependent on a selected frequency of the segmented noise signal to produce a plurality of shifted segmented noise signals. The precise time shift applied to each noise segment considers the frequency content of the segment and the system processing time. Individually for each segmented noise signal, amplitude scaling is applied. The shifted and amplitude-scaled segmented noise signals are then combined to form a composite anti-noise signal which is output into the signal stream to abate the noise through destructive interference.
