    • A method and apparatus for transmitting information from a conversation in a room to a remote listener comprising selecting a structure (101) in the room which is capable of supporting vibration, selecting an electromechanical force transducer (90) which has an intended operative frequency range and comprises a resonant element (84, 86) having a frequency distribution of modes in the operative frequency range, mounting the transducer (90) to the structure (101) using coupling means (68) whereby the transducer excites vibration in the structure, positioning a sensor to detect vibration in the structure (101), determining information from the detected vibration and transmitting said information to a remote listener. There is also provided an anti-eavesdropping system which is the reverse of the method and apparatus according to the first and second aspects of the invention.
