Abstract

Method and apparatus for determining beneficial site(s) for locating bending wave transducer (20) means in operative association with member(s) (10) relying for acoustic operation on resonant modes of bending wave action in such member(s). The method comprises investigative excitation of acoustically relevant bending wave action in a member; and systematic assessment of measurable effect(s) related to such excited bending wave action and corresponding acoustic action, which effects vary according to bending wave transducer location areally of the member concerned. Investigative excitation is by application of acoustic energy to the member concerned so as to induce the acoustically relevant bending wave action with bending wave transducer means selectively operatively associatable areally locally of the member to respond to its bending wave action and the measurable effect(s) being of signals from the transducer means, or by bending wave transducer means selectively operatively associatable areally locally of the member concerned so as to induce the acoustically relevant bending wave action.
