Abstract
Official abstract text for this publication.
An acoustic material is provided which includes a plurality of wood veneers laminated via an adhesive, in which the veneer is impregnated with the adhesive, and the adjacent veneers are substantially in contact with one another. The adjacent veneers are impregnated with the adhesive in an amount of preferably no less than 1 g/m 2 and no greater than 50 g/m 2 per unit area in and around a boundary region of the adjacent veneers. The adhesive may be a water-soluble adhesive or a water-based emulsion adhesive. The veneer may be a rotary veneer, a sawn veneer or a sliced veneer. A musical instrument is further provided which includes a sound board, in which the acoustic material is used as the sound board.
