Interesting wood. I think it might make a good top for an acoustic guitar. The sound radiation coefficient is R=13.5–better than Engelmann Spruce or Western Red Cedar. I probably can’t find it in the US though.

R = SQRT(E/?^3), where E is the Young’s Modulus (Elastic Modulus) and ? is the density (average dried weight). For example, for Batai, R = SQRT(8,53E9 / 360^3) = 13.5. This is an indication of how loudly a panel will radiate sound.
