A tactile-acoustic transducer (1) comprises a vibrator plate (2), microphone means (3) and first (4) and second (5) electrode members which are connected to a source of information (8) through a tuneable network (6). The microphone means (3) are coupled to a computer (10) having display devices (11, 12) and a control output delivering control signals to the tuneable network (6). Rubbing the vibrator plate (2) with the fingertip of his middle finger allows an operator to assess two different states of the transducer, perceived as "stick" and "non-stick" rubbing conditions, the "stick" condition being accompanied by emission of a characteristic sound an occurring when the network (6) is tuned exactly in accordance with the phenomenon or condition of the source to be detected or measured.
