However, there can be no successful implementation without appropriate transducers for transforming acoustic signals into voltages for the electronic control system and for transforming voltages output from the control system into sound. Although a considerable amount of research has been devoted to control algorithms and optimal physical arrangements for sensors and control actuators, little has been written about the requirements for the sensors and actuators themselves. Here a number of practical actuator and sensor implementations are discussed for both fully active and semi active noise control systems.enJournal article00200621272-s2.0-3374877602651821Hansen, C.
