Comparison of Nearfield Acoustic Holography and Dual Microphone Intensity Measurements

  title={Comparison of Nearfield Acoustic Holography and Dual Microphone Intensity Measurements},
  author={Richard W. Bono and David L. Brown and Susan M. Dumbacher},
The measurement accuracy of nearfield acoustic holography (NAH) and dual microphone intensity measurement techniques are examined in terms of source identification capabilities and sound intensity level estimates. Inherent differences in the data acquisition and post processing methodologies are investigated. The techniques are applied according to their individual limitation to best evaluate the test structure. The variance of their respective results and how those results aid in engineering… CONTINUE READING
