Conversion. According to Stevens' definition, a loudness of 1 sone is equivalent to 40 phons (a 1 kHz tone at 40

**dB**SPL). With this exponent, each 10 phon increase (or 10**dB**at 1 kHz) produces almost exactly a doubling of the loudness in**sones**.

Accordingly, how many decibels are in a Sone?

40 decibels

**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.

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.
