Comparing usefulness of acoustic measurements on standing trees for segregation by timber stiffness. (2015)
Presentation / Conference Contribution
Gil-Moreno, D., & Ridley-Ellis, D. (2015). Comparing usefulness of acoustic measurements on standing trees for segregation by timber stiffness. In R. J. Ross, R. Gonçalves, & X. Wang (Eds.), Proceedings: 19th International Nondestructive Testing and EvalThe paper presents a comparison of standard procedures to measure acoustic stiffness of standing trees and logs. The aim is to see how useful they are for predicting the properties of dry, sawn, timber for the purposes of resource segregation in indu...

Potential for estimating the age of instruments by characterisation of wood properties via acoustics. (2014)
Presentation / Conference Contribution
Ridley-Ellis, D., & Popescu, C. (2014, September). Potential for estimating the age of instruments by characterisation of wood properties via acoustics. Presented at WoodMusiCK (FP1302) conference ‘multidisciplinary approach to wooden musical instrumentThe performance of musical instruments is sensitive to several wood properties that are affected by aging. These wood properties also change with temperature and humidity in ways that interact with (and change as a result of) aging processes. This of...

Strength class of minor conifer species, as estimated from log acoustic measurements, small-clear data and knowledge of wood property variation (2014)
Presentation / Conference Contribution
Gil-Moreno, D., Ridley-Ellis, D., & McLean, J. P. (2014, May). Strength class of minor conifer species, as estimated from log acoustic measurements, small-clear data and knowledge of wood property variation. Presented at Experimental Research with Timber:It is well known that wood properties vary from species to species. Additionally, trees grow wood in response to their requirement to grow in a certain environment. Therefore, timber properties also vary by region, by forest practice, and by the chan...
