Abstract: PURPOSE: A vehicle body surface negative pressure measuring apparatus is provided to measure pressure even at the rear portion of vehicle body, while improving signal to noise ratio by effectively eliminating the self-noise generated from a microphone. CONSTITUTION: An apparatus comprises a cap housing(120) arranged to wrap a microphone(110), and which has a hole(122) for measuring noise source formed at the upper portion of the cap housing exposed in the flow direction of external air transmitted through the surface of a vehicle body(100); an open cell type wind screen(130) mounted within the cap housing, and which decreases intensity of air flow by disturbing the flow field without attenuating noise component while the air introduced through the hole of the cap housing is passing; and an isolating pad mounted between the microphone and the side surface of the hole of the vehicle body where the microphone is mounted, and which absorbs the noise and vibration generated from the gap between the vehicle body and the microphone.
