  "textContent": "An audio-signal equalisation device for a vehicle using a data communication bus includes a memory storing speed filter data sets comprising triplets associating a speed value and a gain value associated with coefficients for defining a speed masking filter, and functional filter data sets comprising triplets associating an engine or ventilation value and a gain value associated with coefficients for defining an engine or ventilation masking filter. The device further includes a collector receiving parameters accessible on the communication bus and designating the vehicle speed and a functional parameter selected from the vehicle engine speed and a ventilation data set. The device further includes a computer receiving as an input a noise margin value, and the parameters, to derive therefrom a speed filter data set and a functional filter data set and to combine them in a masking equalisation filter to be applied to the audio signal.",
