\n\tESDU 00002 describes how vibrating plates radiate sound power by
\nsetting the surrounding fluid in motion, and it allows the
\nestimation of the sound power radiated from an isotropic plate to a
\nfluid with properties similar to those of air (low fluid loading).
\nIt covers two types of plate configurations: a single plate and a
\ndouble plate (corresponding to a double wall construction). The
\nability of the single plate to radiate sound power is described by
\nits radiation efficiency which depends on the properties of the
\nplate and of the fluid, the boundary conditions of the plate and
\nthe nearby surrounding structure referred to as a baffle.
\nAnalytical expressions are given that allow the calculation of the
\nradiation efficiency. A number of graphs enable these values to be
\ncorrected for the influence of the boundary conditions and the
\ninfluence of the baffle. For real plate constructions the boundary
\nconditions will be somewhere between simply-supported and clamped.
\nAn auxiliary program, ESDUpac A0002, allows the boundary conditions
\nto be determined approximately from one or several measured
\nresonance frequencies. For a double plate, the fluid in the gap
\nbetween the plates will influence the sound power radiation and a
\ntheory different from that used for the single plate must therefore
\nbe employed. This theory is incorporated in the program, ESDUpac
\nB0002, which allows the estimation of the radiated sound power from
\na double plate construction. Finally, analytical expressions are
\ngiven from which SEA (Statistical Energy Analysis) coupling loss
\nfactors between fluids and plate structures may be calculated. The
\nprograms are provided with this Item. Full details of input and
\noutput formats are given and illustrated by worked examples.\n\t<\/p>\n","protected":false},"excerpt":{"rendered":"
