(1) Sound Propagation Speed and Vibration Attenuation
Wood features high sound propagation speed, which ensures high sound
definition, while its sufficient vibration attenuation (internal loss)
delivers crisp, clear sound. This combination of attributes is impossible
to achieve with conventional materials. |

(2) Uneven Sound Propagation Speed
Another advantage of wood is the uneven sound propagation
speed. Usually, sound propagates at the same speed in all directions,
causing standing waves, resonant points, and poor sound pressure
frequency response. Wood is free of such drawbacks, because the
sound propagates at diverse speeds — faster along the grain than
across.
