TRANSPORT VEHICLE WITH HEAT ENGINE AND METHOD FOR CHARACTERIZING ACOUSTIC EMISSIONS OF SAID VEHICLE

A transport vehicle () comprising:—a heat engine () operable at a number of revolutions varying between a minimum number and a maximum number;—an adjusting device () configured to adjust an infeed flow of air-fuel mixture to the heat engine ();—at least one on-board memory unit () in which an acoustic emission map () of the transport vehicle () is stored, wherein for each data pair comprising a first data item correlated to an operating condition of the adjusting device () and a second data item correlated to the number of engine revolutions, the acoustic emission map () associates, as a function of the first data item and as a function of the second data item, a third data item correlated to an acoustic emission measurement by at least one acoustic sensor (S) external to the transport vehicle () and arranged at a separation distance from the transport vehicle ().
