Soundproofing is an essential component to keeping your spa operating
quietly. Many pumps can run for ten to twenty hours a day during low speed
filtration cycles, creating an annoying hum. You can reduce this annoyance by
selecting a spa that has soundproofing behind all four walls and on the base of
the spa, as well as specifically concentrated between the cabinet and the spa's
pumps and blowers. It’s also helpful to buy a spa that has rubber pads under all
of the pumps, which helps to dampen the sound from vibrations. Proper
soundproofing and rubber pads will dramatically minimize the noises that come
from your spa.
