ABSTRACT:
A device and method for minimizing noise particularly adjacent a source such as a highway. A plurality of transducers (10) are oriented in a specific alignment and driven in a sequence which sends corrective pressure waves so that the noise emanating from the source will be modified upon coaction with the corrective pressure waves emanating from each transducer (10). The transducers (10) themselves include at least one pair of diaphragms (60) that are adapted to move in a arc thereby sending a pulse out from the transducers (10).
