PAVAD B Design and Experimental Results Report
Abstract
The application and experimental results are presented for the Passive and Advanced Vibro-Acoustic Treatments Demonstration, Part B (PAVAD-B) conducted at the Laboratory for Structural Acoustics, Naval Research Laboratory (NRL) during the winter and spring of 2001-2002. The goal of this demonstration is to utilize the most advanced treatments developed in the first part of the program (PAVAD-A), improve their design, and apply them to the Sponsor Supplied Structure. In the initial PAVAD-A study, advanced treatments were applied to an idealized simple supported plate to evaluate the noise reduction performance and optimize the treatment designs. Nearfield Acoustic Holography (NAH) measurements of the untreated Sponsor Supplied Structure were also made and previously reported. These holography data illustrate the structural response and provide a means to determine the optimized PAVAD-B treatment locations. The performance of the improved PAVAD-B advanced treatments is evaluated using these same NAH techniques on the Sponsor Supplied Structure and reported in this document.
