ABSTRACT:
In a laminated construction of a soundboard for use in musical instruments such as the piano, the use of a core having larger shearing elastic modulus and/or smaller shearing loss tangent than that of the fore and rear plates assures small shearing loss in the treble range, and greatly improves the total tonal balance over the entire tonal range.
