The invention relates to a solid wood acoustical board. The solid wood acoustical board comprises fast growing wood battens and an adhesive for adhering the fast growing wood battens. The air-dry density of fast growing wood is below 0.6g/cm3. The solid wood acoustical board is characterized by being porous, and good sound-absorbing effect on medium-high frequency sound waves can be achieved without needing to manually open a hole or groove on the board. Not only are production processes and cost reduced, but also the board made of the fast growing wood with the air-dry density below 0.6g/cm3 has the advantages of being light and wide in applied fields.
