What are Sones
Sone
The sone is a unit of how loud a sound is perceived. The sone scale is linear. Doubling the perceived loudness doubles the sone value. Proposed by Stanley Smith Stevens in 1936, it is a non-SI unit. In acoustics, loudness is the subjective perception of sound pressure. The study of apparent loudness is included in the topic of psychoacoustics and employs methods of psychophysics.
What do the CFM and Sone ratings mean?
In general, there is no good or bad sone rating, as a tolerable noise level usually depends on your personal preference and your noise sensitivity. For those who are looking to compare the sone rating for kitchen range hoods, keep in mind the sones will be higher if the cubic feet per minute (CFM) rating is also higher. CFM measures the amount of air movement generated by a fan; the more air a range hood circulates, the more noise it will make.

How loud should a bathroom fan be?
Bathroom fan sound levels are measured in sones: 4.0 sones is the sound of standard television operation; 3.0 sones is typical office noise; 1.0 sones is the sound of a refrigerator; and 0.5 sones is the sound of rustling leaves. For quiet bathroom ventilation the fan should be rated at 1.0 sones or less.
What is considered a quiet bathroom fan?
