The noise reduction device comprises a sound insulation seat used for placing a weldment and a sound insulation cover used for covering an ultrasonic welding head, the top of the sound insulation seat is provided with an opening, and when the ultrasonic welding head is in contact with the weldment, the bottom of the sound insulation cover is in contact with the top of the sound insulation seat. The sound insulation cover is arranged on a mounting base used for mounting an ultrasonic welding head in a sleeving mode through a fixing piece, and a clamping mechanism is arranged in the sound insulation base. According to the noise reduction device, the sound insulation seat is matched with the sound insulation cover, so that the ultrasonic welding head and a weldment can be sealed between the sound insulation seat and the sound insulation cover when the ultrasonic welding head welds the weldment, the influence of noise generated by secondary friction between the ultrasonic welding head and the weldment on welding
