Abstract
Structure-borne intensities in a vibrating plate radiator having at least one source of vibration are measured without contacting the radiator by producing a pressure hologram of the pressure radiated from the surface of the radiator, determining the normal velocity of the radiator surface from the pressure hologram, and determining at least one component of the structure-borne intensity from the normal velocity.
Claims2
A non-contact method of measuring structure-borne intensities in a vibrating plate radiator having at least one source of vibration, said method comprising the steps of:
- producing a pressure hologram of the pressure radiated from a surface of the radiator;
- determining the velocity of said radiator normal to said surface from said pressure hologram;
- and
- determining at least one vector component of the structure-borne intensity from said velocity of said radiator normal to said surface.
