Nearfield Structure-Borne-Sound Holography

Acoustical Nearfield Holography is a common method for the reconstruction of wave fields in the fluid medium surrounding a vibrating structure. Although NAH has been used to visualize structural vibration since its inception, this has been exclusively done by back-propagating the wave field of the surrounding fluid medium, based on measurement of sound pressure. So far, however, the holographic procedure has not been used to project structure-borne sound fields directly, based on structural vibration measurement. The present research therefore aims at implementing the core concept behind classic Nearfield Acoustical Holography in a structure-borne sound scenario. There is reason to believe that this might open up interesting ways to deal with certain problems in the practice of structural vibration analysis.
