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.

For high-output gas ranges or cooktops, the minimum rate of 1 CFM of ventilation per 100 British thermal units (BTU) is recommended. For example, if your high-output burner output is 45,000 BTU, look for a range hood that provides 450 CFM to best clear the air. However, the higher the CFM, the louder the hood will be.
