A method of reducing a noise level within a compartment of a railway vehicle affected by noise-producing equipment items is provided. The method includes: providing a sound database which relates operational states of the vehicle to respective noise signatures produced by the equipment items; determining the present operational state of the railway vehicle; selecting one or more noise signatures from the database corresponding to the present operational state; creating a noise cancellation signal from the selected noise signatures; and transmitting the noise cancellation signal into the compartment to reduce the noise level within the compartment.
