摘要:

Turbulent pressure fluctuations were measured with piezoelectric pressure transducers which were covered with a 0.125‐in.‐thick elastomer window on a buoyant vehicle. Model predictions (i.e., corrections) were made to account for the turbulent pressure attenuation through the elastomeric coating and spatial averaging effects of a finite transducer. The corrected results were compared with classic turbulent spectral densities measured by others and found to be in good agreement.
