Methods for providing a customized audio experience to a user of an audio output device are provided. A user interface is provided on a user device communicatively coupled to the audio output device, the user interface capable of accepting user input for managing the audio experience for the user. A set of activities is provided via the user interface, wherein each activity in the set invokes a set of behaviors configured for the activity for providing the customized audio experience to the user, wherein each behavior in the set customizes the audio experience for the user. A capability is provided via the user interface for the user to launch an activity from the set for invoking the set of behaviors configured for the activity to receive the customized audio experience.

Provided is an information processing apparatus including a sensor, an actuator, a vibration control circuit, a transmission circuit, and a reception circuit. The sensor detects vibration of a control target. The actuator provides vibration control of the control target. The vibration control circuit generates a drive signal for the vibration control for the actuator according to an output signal of the sensor, and outputs the generated drive signal to the actuator. The transmission circuit modulates transmission data to produce a transmission signal, and synthesizes the modulated transmission signal to produce the drive signal for the vibration control that is to be outputted to the actuator. The reception circuit extracts a reception signal from the output signal of the sensor, and demodulates the extracted reception signal to produce reception data.

An audio system for an ear mountable playback device comprises a speaker, an error microphone predominantly sensing sound being output from the speaker and a feed-forward microphone predominantly sensing ambient sound. The audio system further comprises a voice activity detector which is configured to record a feed-forward signal from the feed-forward microphone. Furthermore, an error signal is recorded from the error microphone. A detection parameter is determined as a function of the feed-forward signal and the error signal. The detection parameter is monitored and a voice activity state is set depending on the detection parameter.

Aspects of the present disclosure provide methods, apparatuses, and systems for closed-loop sleep protection and/or sleep regulation. According to an aspect, sleep disturbing noises are predicted and a biosignal parameter is measured to dynamically mask predicted disturbing environmental noises in the sleeping environment with active attenuation. Environmental noises in a sleeping environment of a subject are detected, input, or predicted based on historical data of the sleeping environment collected over a period of time. The biosignal parameter is used to determine sleep physiology of a subject. Based on the environmental noises in the sleeping environment and the determined sleep physiology, the noises are predicted to be disturbing or non-disturbing noises. For predicted disturbing noises, one or more actions are taken to regulate sleep and avoid sleep disruption by using sound masking prior to or concurrently with the occurrence of the predicted disturbing noises.

A system and method for quieting unwanted sound. As a non-limiting example, various aspects of this disclosure provide a system and method, for example implemented in a premises-based or home audio system, for quieting unwanted sound at a particular location.

An active noise control device includes a first adaptive filter configured to generate a control signal by performing a filtering process on a reference signal corresponding to noise, and a first filter coefficient updating unit configured to update a filter coefficient of the first adaptive filter based on based on the reference signal and an added error signal acquired by adding a first error signal acquired by detecting residual noise by a first microphone and a second error signal acquired by detecting residual noise by a second microphone.

Embodiments include a method and noise cancelling system for cancelling noise in a vehicle by operating at least one noise cancelling means in a first mode of operation to output a noise cancelling signal; receiving at least one input indicative of a state of the vehicle; determining if noise cancelling error conditions are present based on the at least one received input indicative of a state of the vehicle; and operating at least one noise cancelling means in a second mode of operation if noise cancelling error conditions are determined as present.

A headset with automatic noise reduction mode switching is provided to enable better call experience when conducting a call. The headset comprises at least one or more earphones, one or more microphones, a processor, and an active noise cancellation circuit, connected at least with the processor. The processor is configured to determine whether a call is being conducted using the headset, and if a call is being conducted, to switch the active noise cancellation circuit from a first ANC mode to a second ANC mode.

A system including an audio source device having a first microphone and a first speaker for directing sound into an environment in which the audio source device is located and a wireless audio receiver device having a second microphone and a second speaker for directing sound into a user's ear. The audio source device is configured to 1) capture, using the first microphone, speech of the user as a first audio signal, 2) reduce noise in the first audio signal to produce a speech signal, and 3) drive the first speaker with the speech signal. The wireless audio receiver device is configured to 1) capture, using the second microphone, a reproduction of the speech produced by the first speaker as a second audio signal and 2) drive the second speaker with the second audio signal to output the reproduction of the speech.
