How do Sones compare to decibels?
Accordingly, how many decibels are in a Sone?
Secondly, how many Sones is a quiet range hood? Sones to Decibels This is roughly the appropriate range of noise level for your range hood. One sone is a whisper or the noise of a quiet refrigerator. Eight sones is equivalent to a normal conversation or background noise. Therefore, the lower the sone value, the quieter the hood.
Also to know is, what is the difference between sones and decibels?
Sones are not decibels or volume, but rather how sound is sensed. Sones are a linear measurement, like inches. Doubling the sone value is equivalent to doubling the loudness (i.e. one to two, two to four is doubling the sound level twice). Your 4-sone fan will be more than four times a noisy as a 0.9 sone fan.
What does 2 Sones sound like?
The thing to consider with sones is that 2 sones is twice as loud as 1 sone, 4 sones is twice as loud as 2 sones and so forth. In exhaust fans choosing a fan with a sound rating at or below 1 sone will be very quiet. 1 to 2 sones will be heard and anything over 2.5 sones will be noticeable.
