Abstract
A method for managing low frequencies of a loudspeaker located on board a vehicle. The method includes: a step of calibrating an audio system of the vehicle including the loudspeaker, to achieve a set of specifications; a step of measuring acoustic indicators of the loudspeaker including distortion indicator, the measuring step including a step of characterizing the loudspeaker by means of a measuring system, a step of determining a frequency response of the audio system at each volume level, a step of determining a distortion indicator and an indicator of unwanted vibrations for each volume level; a step of managing low frequencies, employing the acoustic indicators, the frequency response at each volume level and the indicators of unwanted vibrations, in the course of which step rendering of the low frequencies by the loudspeaker is optimized. A device for implementing the method is also provided.
