A noise emission reduction system comprising: a shielding member configured to at least partly surround a noise source comprised in a vehicle, the shielding member being a sandwich construction comprising metal sheets (29a-b) and sound dampening material arranged between the metal sheets; a solenoid couplable to the shielding member, and to a frame of the vehicle, the solenoid being controllable to induce vibration of the shielding member in relation to the frame of the vehicle, when the solenoid is coupled to the shielding member and to the frame; a microphone configured to receive sound emitted by the noise source; an accelerometer couplable to the frame; and a controller coupled to the solenoid, to the microphone, and to the accelerometer, the controller being configured to: receive a first signal from the accelerometer; receive a second signal from the microphone; determine a control signal (Sc) for the solenoid based on the first signal and the second signal; and control the solenoid using the determined control signal (Sc) to induce vibration of the shielding member in relation to the frame, when the solenoid is coupled to the shielding member and to the frame, wherein the controller is configured to determine the control signal (Sc) in such a way that the control signal (Sc) results in the solenoid inducing vibration of the shielding member substantially in anti-phase with the sound emitted by the noise source, when the solenoid is coupled to the shielding member and to the frame. a shielding member configured to at least partly surround a noise source comprised in a vehicle, the shielding member being a sandwich construction comprising metal sheets (29a-b) and sound dampening material arranged between the metal sheets; a solenoid couplable to the shielding member, and to a frame of the vehicle, the solenoid being controllable to induce vibration of the shielding member in relation to the frame of the vehicle, when the solenoid is coupled to the shielding member and to the frame; a microphone configured to receive sound emitted by the noise source; an accelerometer couplable to the frame; and a controller coupled to the solenoid, to the microphone, and to the accelerometer, the controller being configured to: receive a first signal from the accelerometer; receive a second signal from the microphone; determine a control signal (Sc) for the solenoid based on the first signal and the second signal; and control the solenoid using the determined control signal (Sc) to induce vibration of the shielding member in relation to the frame, when the solenoid is coupled to the shielding member and to the frame, receive a first signal from the accelerometer; receive a second signal from the microphone; determine a control signal (Sc) for the solenoid based on the first signal and the second signal; and control the solenoid using the determined control signal (Sc) to induce vibration of the shielding member in relation to the frame, when the solenoid is coupled to the shielding member and to the frame, wherein the controller is configured to determine the control signal (Sc) in such a way that the control signal (Sc) results in the solenoid inducing vibration of the shielding member substantially in anti-phase with the sound emitted by the noise source, when the solenoid is coupled to the shielding member and to the frame.
