Abstract

Active noise control is a technique based on the generation of an interfering noise that cancels out harmful noise. This project focused on controlling the vibrations responsible for noise. This strategy has not been applied in industrial settings to date. On this basis, an active noise-control system was developed. It incorporates a sensor that is attached to a vibrating surface and detects the vibration responsible for generating noise. In response to this vibration, the sensor generates an electrical signal transmitted to a computer that controls the production of appropriate counter-vibration.
