摘要:
A simple method is proposed for the absolute calibration of photoacoustic cells using a condenser microphone as a calibrated sound source. This method allows the measurement of acoustical transfer function of resonant and nonresonant cells. By correcting experimental data with the transfer function a good agreement with theoretical previsions has been achieved. The technique was tested on an optically opaque thermally thick sample.
