An air compressor sound prevention apparatus is provided to prevent noise from being generated from vibration of a commercial vehicle when the air compressor is operated. An air compressor sound prevention apparatus includes a detection sensor(10), a controller part(20), and a noise reduction part(30). The detection sensor detects the operation of a steering wheel(2). The controller part receives a detection signal from the detection sensor to calculate a control value and performs a control command by using the control value. The noise reduction part is operated by the controller, and installed between a steering wheel gear box(3) and a power steering pump(4) to reduce operation noise of the air compressor. The noise reduction part includes an auxiliary tank(32) in communication with a first connection line, an auxiliary box part in communication with a second connection line, and an operation valve(36) operated by a motor(35) installed outside the noise reduction part.
