A method and system for determining sound equalisation filters of an audio system having at least one loudspeaker adapted to emit audio signals and a computing device adapted to implement at least one equalisation filter. The system includes modules configured to transmit a measurement signal, and for a first predetermined spatial location, obtain a spectral amplitude curve of a received audio signal, calculate a target spectral amplitude curve, and then make a first determination of a first set of parameterizable equalisation filters which, when applied to the audio signal, reduce a distance between the spectral amplitude curve of the audio signal and the target spectral amplitude curve, and a second determination, from the first set of parameterizable equalisation filters, of a second set of parameterizable equalisation filters, by applying an iterative learning-based method. A first set of optimised equalisation filters is obtained from the second set of parameterizable equalisation filters.

Method and system for determining sound equalising filters of an audio system

An audio system for a seat headrest includes N speaker(s), each configured to be integrated into a seat headrest, N being an integer greater than or equal to 1, and an audio processing device including an electronic transmission channel connected to the speaker(s) and configured to transmit at least one audio stream via the speaker(s). The audio system comprises P microphone(s), each configured to be integrated into the headrest, P being an integer greater than or equal to 1. The audio processing device further includes an electronic receiving channel connected to the microphone(s) and configured to receive at least one sound signal via the P microphone(s).

Audio system for headrest with integrated microphone(s), related headrest and vehicle

An audio system for a headrest having a set of R right speaker(s), a set of L left speaker(s), and an electronic chain configured to emit a sound signal from at least a right input signal and a left input signal. The electronic chain includes a separating module configured to obtain, from the right input signal and the left input signal (L), at least four mono audio components, and a sound spatialization module configured to apply, to each mono audio component delivered by the separating module, a binaural filter previously selected from the plurality of binaural filters, and dedicated to the audio component, producing a sound whose source position is associated with the previously selected binaural filter.
