Evaluation of Attenuation Property of Longitudinal Wave in Wood by Impulse Response
The attenuation property of the wave (longitudinal wave) which propagates in wood is very important for the decision of monitoring area of a sensor. Various factors (species,heterogeneity,length,propagated direction,etc) affect attenuation property,and so we need to know these in detail. Attenuation property and the frequency dependency were investigated by impulse response.
