We took dB measurements with a sound meter with the BEDJET hooked up to the bottom of the bed as shown in the videos. The dB measurements were taken from the top of the bed near the pillow.
We measured 45 dB with the unit on the lowest setting and 49dB with the unit on high. This was in cooling mode, which can be run all night (heating mode is only run for a few minutes at a time). Our team was really pleased with these numbers -- this is quieter than a room fan set on high. Getting to a super quiet unit was a big part of our development and we're really happy the numbers here came out right were we were targeting.
