Split Ductless Air Conditioner Review – The Noise Level of the Outdoor Units.

The noise level of the outdoor units is measured in bels (similar to decibels) on a scale from 0 (sound almost imperceptible) to l3 (pain threshold). Most conditioners and heat pumps operating between 8 and 9 bels, degrees of some units become as low as 6.8. This scale does not seem very large, but consider this: 9 bels sound l0 times more than 8 bels. This means that an air conditioner 9 bels sounds as strong as l0 units to 8 bels. Therefore we think it is advisable to take a little time to compare noise levels.
