Therefore, 1.5 sones is approximately .

A is a unit of loudness , which is a subjective measure of sound. It represents how loud a sound feels to the human ear, rather than the physical intensity of the sound itself. The sone scale was pioneered by psychologist Stanley Smith Stevens in 1936 to create a linear representation of perceived loudness.

When shopping for ventilation fans, range hoods, or HVAC equipment, you will often encounter two different metrics for sound: and Decibels (dBA) . While sones are used to measure perceived loudness, decibels (specifically A-weighted decibels, or dBA) measure the physical sound pressure level. sone to dba verified

If you’ve ever found yourself staring at a technical spec sheet or a noise ordinance manual, you’ve likely encountered two common but very different units of measurement: and dBAs .

Many modern green building codes (like LEED or WELL) require ventilation fans to stay under a specific Sone level to ensure occupant comfort. The sone scale was pioneered by psychologist Stanley

While acoustics experts note that a perfectly universal conversion does not exist for complex broadband noise due to how our ears interpret different frequencies, the standard conversion formula adopted across the ventilation and appliance industries is:
