NOISE EMISSION REDUCTION SYSTEM

A noise emission reduction system (7) comprising: a solenoid (11) couplable to a shielding member (9), and to a frame (3) of a vehicle (1), the solenoid (11) being controllable to induce vibration of the shielding member in relation to the frame of the vehicle; a microphone (13) configured to receive sound emitted by a noise source (5); an accelerometer (15) couplable to the frame (3); and a controller (17) coupled to the solenoid (11), to the microphone (13), and to the accelerometer (15), the controller being configured to: receive a first signal (S1) from the accelerometer (15); receive a second signal (S2) from the microphone (13); determine a control signal (Sc) for the solenoid (11) based on the first signal (S1) and the second signal (S2); and control the solenoid (11) using the determined control signal (Sc) to induce vibration of the shielding member in relation to the frame.
