Industrial valves produce noise due to two main causes: mechanical work, movement, and vibration within the valves, and u-ids owing through the valves [4–6]. There are two nega-tive eects of noise: acoustic fatigue and hearing damage [7–9]. The noise, however, may be benecial as a sign of an abnormal condition within the valve. Due to the nega-
