Sones Rating
What is a 'Sone' rating?
Acoustic Performance Metrics
A measure of perceived loudness. A rating of 1.0 is roughly equal to a quiet refrigerator. High-end 1200 CFM blowers can reach 10+ Sones; we use silencers (inline mufflers) to drop this to manageable levels.
The measurement of perceived loudness; professional-grade blowers aim for under 2.0 sones at working speeds.
