Volume 27, Issue 2 , June 2012, , Pages 306-318

https://doi.org/10.22092/ijwpr.2012.117069

Abstract
  The acoustic behavior of reaction and normal woods, phase velocity, group velocity and attenuation coefficients in the main directions for two wood species (Populus deltoids & Picea abies), were measured and compared. The results did not show any significant difference between phase velocities of ...  Read More
