An information processing device includes circuitry that detects a change in a position of a person. The circuitry also changes a position of a virtual sound source in accordance with the change in the position of the person and outputs a sound through wave field synthesis so that a spatial sound field is transmitted via a plurality of speakers.

The systems and methods described relate to the concept that smart devices can be used to: sense various types of phenomena like sound, blue light exposure, RF and microwave radiation, and, in real-time, analyze, report and/or control outputs (e.g., displays or speakers). The systems are configurable and use standard computing devices, such as wearable electronics (e.g., smart glasses), tablet computers, and mobile phones to measure various frequency bands across multiple points, allowing a single user to visualize and/or adjust environmental conditions.

Disclosed is a headset for audio communication, a software application for an electronic device associated with a headset, and a method for controlling a headset feature. The headset is configured to be worn by a user. The headset comprises a speaker for sound transmission into the user's ear, a transceiver or a radio communication unit for communication with an external device, a connection to a location-based service software, the location-based service software is configured for controlling at least one headset feature based on location data of the headset, and a processing unit. The processing unit is configured for enabling the location-based service software to detect if the current location data of the headset indicates a change in location data corresponding to a certain change criterion and changing the at least one headset feature, if a change criterion associated with the change in location data is satisfied.

Embodiments of this application provide a user hearing protection method, apparatus, and electronic device. In the user hearing protection method, after an electronic device enables a hearing protection mode, when an audio output mode is a headset output, sound pressure output by the headset is obtained based on current-frame sound source data; when the sound pressure is greater than a predetermined sound pressure threshold, an instantaneous sound pressure over-standard warning is performed, and an instantaneous sound pressure over-standard protection operation is performed on the electronic device, and a user's hearing can be protected when the instantaneous sound pressure exceeds a standard. In addition, after the output sound pressure is obtained, the sound pressure may be stored, and a sound dose accumulated to a current moment may be determined based on the stored historical sound pressure data; when the sound dose is greater than a predetermined sound dose standard value, sound dose over-standard warning and a sound dose over-standard protection operation are performed, to implement early warning and hearing protection for a user when a total sound dose exceeds a standard after music is listened continuously for a long time.

A differential MEMS-readout circuit comprises a first input bonding pad, including a first contact pin and a second contact pin. The differential MEMS-readout circuit comprises a second input bonding pad, including a first contact pin and a second contact pin; and a differential-readout amplifier section comprising a first input connected to the first contact pin of the first input bonding pad and a second input connected to the first contact pin of the second bonding pad, wherein the differential-readout amplifier section comprises a first and a second transistor circuit and each of the second contact pins of the first and second input bonding pads is coupled to one of the first and the second transistor circuits or is coupled to one of the first and the second transistor circuits and/or to ground.

A sound input-output control apparatus that can provide wider usage to a sound output apparatus are provided. The sound input-output control apparatus includes a distance determination unit configured to determine whether the distance between at least two of a plurality of sound output apparatuses each independently mounted on a user and configured to output sound toward the user is equal to or longer than a predetermined distance, and an operation control unit configured to control each of the sound output apparatuses to perform first operation when the distance between at least two of the plurality of sound output apparatuses is shorter than the predetermined distance, and control each of the sound output apparatuses to perform second operation when the distance between at least two of the plurality of sound output apparatuses is equal to or longer than the predetermined distance.

An audio signal processing apparatus is provided. The audio signal processing apparatus includes an input terminal receiving an input audio signal, a processor obtaining a difference between a playback loudness of the input audio signal and a desired loudness thereof and correcting a frequency band spectrum of an output audio signal for each of a plurality of frequency bands based on the difference between the playback loudness and the desired loudness of the input audio signal and a relationship between a loudness and a sound pressure for each of the plurality of frequency bands, and an output terminal outputting the output audio signal. The playback loudness is a loudness of the output audio signal when the input audio signal is output without the correction.

Audio data is generated for a vehicle audio system using a portable computing device. Vehicle parameter data is received at the portable computing device from a vehicle. Sound parameter data is generated from the vehicle parameter data. Audio data is generated using a synthesizer based on the sound parameter data. The generated audio data is transmitted to the vehicle audio system from the portable computing device.

In one aspect, a device may include at least one processor and storage accessible to the at least one processor. The storage may include instructions executable by the at least one processor to identify at least one characteristic associated with audio as sensed at a first location, with the audio being produced at a second location that is different from the first location. The instructions may also be executable to, based on the at least one identified characteristic, adjust a first volume level of a first component of the audio in a first frequency and/or first frequency band but not a second volume level of a second component of the audio in a second frequency and/or second frequency band of the audio.

A system, such as an ear-wearable device or a hearing aid, can receive multiple audio signals representing a same audio content, can cross-correlate the multiple audio signals to determine relative delays between the audio signals, can apply the determined delays to at least one of the audio signals to form multiple synchronized audio signals, and can mix at least two of the synchronized audio signals in time-varying proportions to form an output audio signal. The system can optionally adjust the mix proportions, in real time, to increase or optimize the signal-to-noise ratio of the output audio signal. The system can optionally perform the cross-correlation repeatedly, at regular or irregular time intervals, to update the relative delays. The system can optionally divide the audio signals into frequency bands, and apply these operations to each frequency band, independent of the other frequency bands.
