A unit that rates sound level, used to define exhaust fan noise.

Things you need to know

The lower the sone rating, the less noise the fan makes. One sone is roughly equivalent to the sound of a refrigerator in a quiet kitchen. Fans with a 2 sone rating are considered quiet.

Cost Considerations

The lower the sone rating, the more expensive the fan.
