What Is A Sones Upd -

You might ask yourself, "What is a sones? And why do I care how many of them my fan has?"

A common misconception is that sones are simply an alternative to decibels. They are not alternatives; they are different types of measurement. Decibels are objective, measurable with a microphone, and tell you the physical energy of a sound. Sones are subjective, derived from listening tests with human subjects, and tell you how that sound will likely be perceived. You cannot directly convert decibels to sones without knowing the frequency and level of the sound, because human hearing is not equally sensitive to all frequencies (a concept captured by the "phon" unit, which is the loudness level in decibels of a 1,000 Hz tone judged equally loud). what is a sones

: This makes the measurement more intuitive. If you double the sone value, the sound will seem twice as loud to you (e.g., 2 sones sounds twice as loud as 1 sone). You might ask yourself, "What is a sones

The defining reference point for the sone scale is simple and elegant. One sone is defined as the loudness of a 1,000 Hz (a mid-range frequency, similar to a high female voice) tone at 40 decibels above the standard threshold of hearing. In practical terms, the sound of a quiet refrigerator humming in a silent kitchen is roughly 1 sone. From this anchor point, the scale operates on a principle of multiplication, not addition. Decibels are objective, measurable with a microphone, and
