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.
Aluminium sheet thickness has been calculated from ultrasonic data obtained using a sendΒ±receive, radially polarised electromagnetic acoustic transducer (EMAT). Sheets in the thickness range between 0.1 and 0.5 mm have been measured using this noncontact approach at a stand-o of up to 1.5 mm. Normal
