A measurement system that provides to perform air leakage tests of motor vehicles, at the same time to measure a door displacement amount that causes wind-induced noise, the wind-induced noise and the air leakage, the measurement system comprising: - at least one compressor that provides the required air for the air leakage test, - at least one pump that pumps the air provided by the compressor into the vehicle for test, that sucks the air in the vehicle in the suction direction by operating backwardly, - at least one air transmission line that passes through the air flow between the vehicle and the pump, provides the air directed by the pump to be transferred to the vehicle, preferably has a tubular form and is portable, - at least one link adaptor that is located on one end of the air transmission line or attached to its one end, provides the connection of the air transmission line to the vehicle imperviously, - at least one pressure sensor that is located within the vehicle and/or within the air transmission line, that measures the pressure value within the vehicle and outside the vehicle, characterized in that it further comprises: - a distance meter that measures via laser beams the door displacement amount of the door that is opened outwardly by means of the air pressure applied into the interior volume of the vehicle, - an acoustic camera that measures the noise frequency that occurs during the door displacement, - a control unit adapted to control the test process and that provides to create a preferred air pressure and volume value within the vehicle during the test by controlling the operation of the compressor and the pump according to the measurement value that is received from the pressure sensor, controls the door opening amount that is opened outwardly according to the measurement value that is received from the distance meter and the camera, if the door opening amount is above a preferred set value, saves the instant pressure value, the door opening amount, and determines the simulated speed value of the vehicle according to the pressure. - at least one compressor that provides the required air for the air leakage test, - at least one pump that pumps the air provided by the compressor into the vehicle for test, that sucks the air in the vehicle in the suction direction by operating backwardly, - at least one air transmission line that passes through the air flow between the vehicle and the pump, provides the air directed by the pump to be transferred to the vehicle, preferably has a tubular form and is portable, - at least one link adaptor that is located on one end of the air transmission line or attached to its one end, provides the connection of the air transmission line to the vehicle imperviously, - at least one pressure sensor that is located within the vehicle and/or within the air transmission line, that measures the pressure value within the vehicle and outside the vehicle, characterized in that it further comprises: - a distance meter that measures via laser beams the door displacement amount of the door that is opened outwardly by means of the air pressure applied into the interior volume of the vehicle, - an acoustic camera that measures the noise frequency that occurs during the door displacement, - a control unit adapted to control the test process and that provides to create a preferred air pressure and volume value within the vehicle during the test by controlling the operation of the compressor and the pump according to the measurement value that is received from the pressure sensor, controls the door opening amount that is opened outwardly according to the measurement value that is received from the distance meter and the camera, if the door opening amount is above a preferred set value, saves the instant pressure value, the door opening amount, and determines the simulated speed value of the vehicle according to the pressure. - a distance meter that measures via laser beams the door displacement amount of the door that is opened outwardly by means of the air pressure applied into the interior volume of the vehicle, - an acoustic camera that measures the noise frequency that occurs during the door displacement, - a control unit adapted to control the test process and that provides to create a preferred air pressure and volume value within the vehicle during the test by controlling the operation of the compressor and the pump according to the measurement value that is received from the pressure sensor, controls the door opening amount that is opened outwardly according to the measurement value that is received from the distance meter and the camera, if the door opening amount is above a preferred set value, saves the instant pressure value, the door opening amount, and determines the simulated speed value of the vehicle according to the pressure.
