Sound Levels What Creates Increased Noise Levels...- Hot tub equipment is not housed behind the insulation but just behind the cabinet.
- Oversized equipment, to much power for the number of jets in the design.
- To much horsepower; extra volume of water with no extra hydrotherapy benefit due to the fact that there is only a maximum amount of water the pipes can handle at any given time.
- Also having the equipment on the outside of your hot tub may provide better access, but it comes at a loss of peace and a cost in energy efficiency.
Keep in Mind These Levels To Understand Just How Loud These Hot Tubs Are In Comparison. Jet engine at 100........................................................140dB Sandblasting, Loud Rock Concert..................................115dB City Traffic (inside car)...................................................85dB Telephone dial tone.......................................................80dB Normal conversation at 3’.........................................60-65dB Whisper Quiet Library at 6’............................................30dB Here Are The Results... The testing of these hot tubs was done in a side-by-side comparison with proper professional sound testing equipment; each hot tub was tested with the Cover off and for an equal amout of time. |
