A motor vehicle (1) comprises a sound emitting instrument (7) for emitting sound comprising an aerophone instrument (8) arranged so as to be constantly invested by an aerodynamic flow corresponding to a forward motion of the motor vehicle, whereby the aerophone instrument (8) is configured to emit at least part of said sound passively through the aerodynamic flow, and an active device (17, 18, 19, 25) configured to actively control at least one property of the sound, characterized by comprising a control apparatus (ECU), in turn comprising a mapping to associate a speed of the motor vehicle (1) with a desired value of a variable corresponding to the property, the control apparatus being configured to determine the speed of the motor vehicle (1), determine the desired value of the variable by applying the mapping to the determined speed, control the active device (17, 18, 19, 25) as a function of the desired value according to a control law to reduce a deviation between an actual value of the variable and the desired value.
