Sound board assembly for musical instruments

A sound board assembly for a musical instrument, comprising:

• a plurality of straight grain wood veneers joined together in a first plane to form a plate unit having at least first and second surfaces, each of the wood veneers extending in a direction along the grain of the wood veneer and arranged in parallel relation to each other, and
• a plurality of voids formed in the plate unit, wherein the plurality of voids are selectively arranged in the plate unit in accordance with a property E/G, where E represents the modulus of longitudinal elasticity and G represents a modulus of rigidity.
