Title: Sonic wood testing apparatus and method

Patent ·
OSTI ID:5725882

A non-destructive sonic testing apparatus is described for ascertaining the integrity of wooden members comprising: means for receiving sonic energy imparted to the wooden member and generating a signal in response to the received sonic energy; analyzing means for receiving the signal and performing an analysis to determine energy levels as a function of frequency for the signal. The analyzing means also are operative to determine at least two criteria selected from the group comprising the mean, mode, median and range for the energy levels as a function of frequency and to determine the relative relationship between the two criteria, means responsive to the relative relationship between the two criteria to provide a visual indication representative of the condition of the wooden member.
