In respect to this, how loud is a 4 sone fan?
The lower the sone value, the more comfortable the listening environment will be. For your question, a 4-sone rating is about four times a loud as a 0.9 (~1) sone rating. Sones are not decibels or volume, but rather how sound is sensed. Sones are a linear measurement, like inches.
Beside above, what does 8 sones sound like? One sone is similar to a whisper or the sound of an extremely quiet refrigerator or dishwasher. Eight sones are equivalent to a normal conversation or background noise. The lower the sone value, the quieter the hood.
Similarly one may ask, how many sones is a fridge?
Sound levels are rated in sones where the lower the rating number, the quieter the fan. Typical economy fans are rated at about 4.0 sones or more while any fan rated 1.0 sones or less is very quiet (1.0 sones is roughly equivalent to a modern refrigerator).
How noisy is a sone?
The Home Ventilating Institute (HVI) defines a sones this way: “In technical terms, a sone is equal in loudness to a pure 1,000 Hertz per second tone at 40 decibels above the listener's threshold of hearing. In exhaust fans choosing a fan with a sound rating at or below 1 sone will be very quiet.

What is the sone scale?
The sone scale is a third scale associated with the loudness of a sound. The sone scale is based on the observation that a 10 phon increase in a sound level is most often perceived as a doubling of loudness. According to the sone scale, a 1 sone sound is defined as a sound whose loudness is equal to 40 phons.What is CFM in exhaust fan?
Air movement is typically measured in cubic feet per minute (CFM). Ventilation rates based upon eight air changes per hour are generally suggested. For most bathrooms this works out to one CFM per square foot of bathroom area. For example, a 7' x 10' bathroom would require a 70 CFM fan.What are sones in range hoods?
Range Hood Sound LevelsThe sound that a range hood makes is measured in sones. One sone is roughly equal to the sound of a refrigerator running. Normal conversations take place at about 4 sones and light traffic rates up to around 8.
