Sones: Definition !!hot!!
A fan rated at 4 sones sounds exactly twice as loud as a fan rated at 2 sones. But a 50 dB fan does not sound twice as loud as a 40 dB fan (it takes about a 10 dB increase to perceive a doubling of loudness). The Sones to Decibels Conversion (Approximate) Since sones and decibels measure different things, conversion isn’t exact. However, for typical fan noise (mid-to-high frequencies), this table is widely accepted:

If you’ve ever shopped for a bathroom exhaust fan, a range hood, or an industrial blower, you’ve probably seen a specification labeled “sones.” But unlike decibels (dB), which most people have heard of, sones remain a mystery to many. A fan rated at 4 sones sounds exactly
