Noise Level

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. Fan noise is affected by the speed and profile or shape of the blade. View the dBA of each model below.
