Abstract
Noise in the locomotive cab arises from the work force and the auxiliary units, the interaction of the wheels with the rails when driving, aerodynamic noise from the air flow near the cockpit. At the time of opening the window in the cab of the locomotive is a sharp increase of the speed of pressure caused by the nature of the airflow. When closing the windows in the cabin of the vehicle is a process of a sharp decline in the speed and pressure of the air wave energy dissipation.
