An acoustic resonance technique has been evaluated as a means of detecting deterioration in wood poles. The basis of the technique is that degradation of the pole by rot or other agency will lead to an increase in the damping of longitudinal acoustic waves, which can subsequently be detected by an e
Wood poles have been traditionally tested by "sounding" -striking with a hammer and making a subjective assessment on the basis of the sound emitted. Various other acoustic methods have been developed and employed for this function but none has been accepted on any regular basis as being successful.
It is important to have correct information regarding particle size in order to interpret, control, and optimize many industrial processes. Prior to the recent advent of acoustic attenuation spectroscopy, it was difficult to study particle size distribution online and under real process conditions i
