1, different manufacturing processes
Veneer: refers to the board formed by direct cutting of wood.
Double board: refers to the composite board, which is formed by vertically and horizontally pasting multiple thin plates together.
2. Different lines
Veneering: Irregular grain, caused by natural growth.
Double board: it is artificially compressed, indicating that the wood grain rules of wood-based panels are very regular.
3. Different components
Veneering: natural wood is used, and the internal structure is more natural and compact.
Double board: made of artificial wood (made of sawdust and powder by high pressure), and three layers of interlayer can be clearly seen on the sound hole.
4. Different timbres
Single board: the frequency of vibration will be richer and clearer than that of double board, with rich volume and balanced frequency response.
Double board: the frequency of vibration will be unnecessary loss and irregular, or the vibration will be uneven, resulting in the timbre of double board is not as good as that of single board.
