The invention discloses a wooden acoustic board resistant to impact. The wooden acoustic board resistant to impact comprises an acoustic insulating material layer at the uppermost layer, a tackiness agent in the middle layer and a high-strength fiber layer at the bottommost layer, wherein the acoustic insulating material layer is made of acoustic insulating cotton, the high-strength fiber layer is made of glass fibers, the acoustic insulating material layer accounts for 74%-80% of the overall weight of the wooden acoustic board resistant to impact, the tackiness agent accounts for 5%-9% of the overall weight of the wooden acoustic board resistant to impact, and the high-strength fiber layer accounts for 14%-20% of the overall weight of the wooden acoustic board resistant to impact. The wooden acoustic board resistant to impact has the advantages of being light in material, free of deformation, high in strength, highly resistant to impact and the like.
