摘要:
A probe‐tube microphone has been developed for use in the harsh experimental environment involved in studying small‐scale pressure fluctuations in combustion magnetohydrodynamics. A smooth frequency response is obtained by a theoretically derived method of impedance matching where an acoustical resistance is placed midway within the length of the tube. The use of such probe‐tube microphones under experimental conditions has proven very satisfactory.
