Potential for estimating the age of instruments by characterisation of wood properties via acoustics. (2014)
Presentation / Conference Contribution
Ridley-Ellis, D., & Popescu, C.-M. (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 instrument identification’

The 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: Cost action FP1004

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...
