What Is A Sones -

: You will most often see sones used to rate the noise levels of household appliances like bathroom fans and kitchen range hoods . Common Sone Ratings

Because the scale is linear, you don't need a degree in acoustics to compare products. If Fan A is rated at 2.0 sones and Fan B is rated at 4.0 sones, you know immediately that Fan B is twice as loud.

Because the scale is linear, it is much easier for consumers to interpret than decibels: Half as loud as 1 sone. what is a sones

So why use sones instead of decibels? The answer lies in practical application. For engineers designing quieter products, decibels are perfect for measuring absolute sound pressure. But for consumers and human-centered design, sones are often more useful. You will most frequently encounter the sone rating on the packaging of household appliances that produce continuous, predictable noise, such as:

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). : You will most often see sones used

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

Have you ever bought a fan that was way too loud? Let us know in the comments below if you check sones ratings before your next purchase! Because the scale is linear, it is much

When you ask "what is a sones," you are really asking "how annoying will this fan be?"

This relationship—where a 10 dB increase corresponds to a doubling of sones—holds roughly for mid-range frequencies and typical sound levels.
