Definitions

The active control of sound is realized with active noise reduction systems. These systems are made up of actuators, sensors and digital signal processing. Unlike classical passive sound control the active control of sound is especially effective at low frequencies. Active noise reduction systems are able to reduce unwanted sound with a minimum of added mass and volume which makes them useful for lightweight applications for example in the automotive or aerospace industry.
