Hot tub pumps are not very loud, especially on low speed. The single-speed pump and the dual-speed pumps while on low speed are way under 50 dB when measured just a few feet away. The noise level only exceeds 50 dB if the reading is taken less than 12 inches from the running pump. On high speed, the two-speed pumps’ noise levels are quiet enough that even if placed near the tub, they do not inhibit conversation between the tub occupants or cause the need to yell.
