Narrowband sound power measurement using supersonic intensity in underwater reverberant environments

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

A vibrating thin-walled cylinder was submerged and scanned using a custom built pressureacceleration intensity probe. Measurement mesh density was increased and standoff distance between the sensors and cylinder was decreased from the previous work (presented at InterNoise 2006) to improve the results. A new intensity probe was developed with reduced EMI rejection in its noise floor. In addition, reverberant signal separation post-processing techniques were implemented in the wavenumber domain. Results show that the reverberation field in the tank can be filtered from the hologram data, and that supersonic intensity can be used to compute narrowband radiated sound power and directivity.
