A hearing protection apparatus, a related method, and a server device is disclosed. The hearing protection apparatus comprises a set of microphones comprising a first microphone and a second microphone; a first positioning device for provision of first position data of the hearing protection apparatus; and a communication device connectable to the first microphone and the second microphone and the first positioning device, the communication device comprising a processing unit and an interface; wherein the processing unit is configured to: obtain a first audio input signal from the first microphone and a second audio input signal from the second microphone; determine first audio data based on the first audio input signal and the second audio input signal; and transmit the first audio data and the first position data to a radio unit.

An apparatus including circuitry configured to: obtain two or more audio signals from respective two or more microphones; determine, in one or more frequency band of the two or more audio signals, a first sound source direction parameter and first sound source energy parameter based on processing of the two or more audio signals; determine, in the one or more frequency band of the two or more audio signals, a second sound source direction parameter and second sound source energy parameter based on processing of the two or more audio signals; obtain a region defining a direction and/or range for a filter; and generate the filter to be applied to the two or more audio signals, wherein filter gain/attenuation parameters are generated based on the region in relation to the first sound source direction parameter, the first sound source energy parameter, the second sound source direction parameter and the second sound source energy parameter.

Methods for rendering audio for playback by two or more speakers are disclosed. The audio includes one or more audio signals, each with an associated intended perceived spatial position. Relative activation of the speakers may be a cost function of a model of perceived spatial position of the audio signals when played back over the speakers, a measure of proximity of the intended perceived spatial position of the audio signals to positions of the speakers, and one or more additional dynamically configurable functions. The dynamically configurable functions may be based on at least one or more properties of the audio signals, one or more properties of the set of speakers and/or one or more external inputs.

In a method for determining a head related transfer function an audio source outputs a source audio signal, namely both acoustically as a sound signal and also non-acoustically as a data signal. The sound signal is received by the hearing aid of a user and is converted by this hearing aid back into an audio signal, namely into a first audio signal, wherein the data signal is received by the hearing aid or by another device, which generates a second audio signal from the data signal, wherein the first audio signal and the second audio signal are compared to one another and the HRTF is determined based thereon. There is also described a corresponding hearing aid.

The scale of an apparatus that reproduces a sound field is reduced. A speaker array 1 includes a plurality of speakers arranged at intersections of a first plurality of virtual lines arranged parallel to each other at equal intervals and a second plurality of virtual lines that are perpendicular to the first plurality of virtual lines and are arranged parallel to each other at equal intervals, wherein multipoles of a given order are superimposed using the plurality of speakers to realize wave field synthesis.

A method includes: receiving multi-channel sound source signals from a microphone array; synchronizing the multi-channel sound source signals based on spatial information of the microphone array; and detecting an abnormal channel of the microphone array by inputting the synchronized sound source signals and first conditional information to a neural network model configured to perform an inverse operation.

Embodiments relate to binaural spatialization of more than two sound sources on two audio channels of an audio system. Sound signals each emitted from a corresponding sound source are collected, and a respective virtual position within an angular range of a sound scene is assigned to each sound source. Multi-source audio signals are generated by panning each sound signal according to the respective virtual position. A first multi-source audio signal is spatialized to a first direction to generate a first left signal and a first right signal. A second multi-source audio signal is spatialized to a second direction to generate a second left signal and a second right signal. A binaural signal is generated using the first left signal, the second left signal, the first right signal, and the second right signal. The binaural signal is such that each sound source appears to originate from its respective virtual position.

A remote assistance system comprises a remote facility configured to assist an operation of a vehicle. A processor of the vehicle executes data processing of surrounding environment data of the vehicle, and transmission processing to transmit data for communication indicating the processed data by the data processing to the remote facility. The surrounding environment data includes sound data of the surrounding environment of the vehicle. In the data processing of the surrounding environment data, a type of a sound source included in sound data is estimated by an acoustic analysis of the said sound data. Subsequently, identification data corresponding to the estimated type is specified by referring to a database of the vehicle using the estimated type, and this is added to the data for communication.

An audio system and a method of determining an audio filter based on a position of an audio device of the audio system, are described. The audio system receives an image of the audio device being worn by a user and determines, based on the image and a known geometric relationship between a datum on the audio device and an electroacoustic transducer of the audio device, a relative position between the electroacoustic transducer and an anatomical feature of the user. The audio filter is determined based on the relative position. The audio filter can be applied to an audio input signal to render spatialized sound to the user through the electroacoustic transducer, or the audio filter can be applied to a microphone input signal to capture speech of the user by the electroacoustic transducer. Other aspects are also described and claimed.

One example may include a method that includes receiving, at a presentation server, an audio data signal from a mobile device located in a presentation space, identifying a mobile device identification characteristic of the mobile device based on the received audio data signal, determining a mobile device location via a location determination procedure, and playing the audio signal via a loudspeaker.
