Abstract In order to develop criteria for the physical evaluation of wood for soundboards of musical instruments, measurements were made of dynamic Young's modulusE′, static Young's modulusE, internal frictionQ −1 in longitudinal direction, and specific gravityγ for numerous species of broad-leaved wood. From the results obtained, including those of our previous paper on coniferous wood [1], it was found that the suitability of wood for soundboards could be evaluated by the quantity ofQ −1/(E′/γ), and that there were very high correlations betweenQ −1/(E′/γ) andE′/γ, and betweenE′ andE, regardless of wood species. Consequently, it becomes possible to select practically any wood suitable for soundboards by using the value ofE/γ, which can be measured easily, and it was derived that the relation betweenE′/γ andQ −1 of wood could be expressed by an exponential equation regardless of wood species.
