Abstract
PURPOSE: To effectively prevent occurrence of the peak of detected acoustic pressure and attenuation at high frequency band sound by making the resonant frequency of a microphone probe approx. equal to the frequency of the vibration of a sound pressure tube.
CONSTITUTION: A microphone probe is constructed by forming double water cooling jackets 2 and 3 around a sound pressure tube 1 having 5mm of inner diameter and 80mm of length, connecting a casing 5 containing a condenser microphone having 23.8mm of outer diameter at the rear end of the tube 1, fixing the tube 1 and the casing 5 to flanges 6, 7, respectively formed at the end surfaces thereof, and forming a water jacket 8 around the casing 5. A sound absorbed 9 is filled in approx. 25mg over approx. 10mm from the rear end of the tube 1 to the front end thereof.
