The utility model discloses a massage armchair air bag noise reduction structure, which comprises a chair frame, an air bag, an air pump, an air pipe and an air valve, the air bag, the air pump, the air pipe and the air valve are arranged in the chair frame, the air bag is communicated with the air pump through the air pipe, the air valve is provided with a ventilation part, and the ventilation part is communicated with the air pipe to control the on-off of the air pipe between the air bag and the air pump. The device further comprises an air leakage pipe which is communicated with the ventilation part. A silencing air tap is arranged on the air leakage pipe, and the inner hole diameter of the silencing air tap is smaller than that of the air leakage pipe; and when the air bag is deflated, air flow is exhausted after passing through the silencing air nozzle. Therefore, the air leakage airflow of the air bag is not directly discharged into the air in a large impact manner, but is discharged into the air after
