Abstract: The present invention; It is about the method developed to reduce noise in machines such as compressors that compress air and gases to higher pressures, and compressors and generators that emit high noise, such as generators that convert mechanical energy into electrical energy, using the active sound suppression method, and the device designed by positioning according to this method. The system developed with the present invention is a noise reduction method in high-noise machines and includes ANC integrated (200), microphone (100), loudspeaker (400), and is mainly used in machines such as generators and compressors.
