PROBLEM TO BE SOLVED: To reduce noise in a sensor system, using transducers. SOLUTION: The sensor system (20) includes a transducer array (22) having a plurality of transducers (40, 70, 102, 142), a selector (28) coupled with the transducer array (22), and an output processing subsystem (32). An output transmission path (46, 78, 104), associated with the individual transducer (40, 70, 102, 142), is defined between each transducer (40, 70, 102, 142) and the output processing subsystem (32). The selector (28) applies control signals (34) to the transducer array (22), to cause the array (22) to have at least one selected transducer (40, 70, 102, 142) and at least one unselected transducer (40, 70, 102, 142). The system (20) is configured so that for a selected transducer (40, 70, 102, 142), the output transmission path (46, 78, 104) for that transducer (40, 70, 102, 142) is enabled, so as to permit output signals to be transmitted from the selected transducer (40, 70, 102, 142) to the output processing subsystem (32).
