A method for processing an electrical signal for an acoustic emission system. The method carried out by the system includes the following steps: a) transmitting a calibration signal to the electroacoustic transducer; b) emitting a sound based on the calibration signal, by the electroacoustic transducer; c) measuring the voltage across the terminals of the load; d) calculating the variation in impedances of the electroacoustic transducer as a function of the variation in frequencies of the calibration signal; e) determining the resonant frequency of the electroacoustic transducer from the variation in calculated impedances; f) selecting a set of acoustic filters in the database based on the determined resonant frequency; and g) applying the set of acoustic filters to the electrical signal in order to process the electrical signal coming from the input.

Method for processing a signal from an acoustic emission system of a vehicle and vehicle comprising this acoustic emission system

An audio processing method and system for a seat headrest audio system, the audio system including at least two speakers positioned on opposite sides of the headrest, the method including detecting a position of the user's head and adjusting a first set of parameters of at least one audio processing operation as a function of that position. The method includes determining a user characteristic and/or temporary state of the user, selecting an audio settings profile related to that characteristic, the audio settings profile including a second set of prerecorded audio profile parameters, and adjusting a third set of audio parameters effectively applied to control the audio rendering of each speaker, based on the first and second sets of parameters.

An electronic device for controlling the broadcasting of digital audio and/or video streams that includes: a module for receiving a list of upcoming streams able to be broadcast; a module for acquiring a set of profile(s) of a group of user(s); a module for detecting, among the received list and based on the acquired set, a preferred digital stream intended to be broadcast after a current digital stream; and a module for switching from a broadcast of the current stream to a broadcast of the preferred stream. The detection module is configured to detect an event triggering a switch to the preferred stream, and the switching module is configured to operate at least according to an automatic mode, where it is able to switch from the broadcasting of the current stream to that of the preferred stream upon the detection of the triggering event.

An electronic device for receiving a radio signal includes an upstream amplifier configured to amplify a received radio signal, a control module configured to control a gain of the upstream amplifier, and a mixer connected at the output of the upstream amplifier and configured to mix the signal from the upstream amplifier with a reference signal. The control module is further configured to perform an intermodulation detection, by commanding the generation by the upstream amplifier of a gain increase and comparing a first power with a second power, the first and second powers being respective powers of a signal at the output of the mixer, the first power being measured in the absence of gain increase and the second power being measured in the presence of the gain increase.
