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).
Four times louder than 1 sone; equivalent to a face-to-face conversation. Sones vs. Decibels (dB)
Twice as loud as 1 sone; comparable to a normal office environment.
A is a linear unit of loudness that measures how humans subjectively perceive the intensity of sound. Unlike decibels, which measure physical sound pressure on a logarithmic scale, the sone scale is designed to be more intuitive: doubling the sone value directly corresponds to a doubling of the perceived loudness. Understanding the Sone Scale 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
These fans move massive amounts of air to cool your entire home.
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
The lower the sones, the quieter the unit. For residential appliances:
The short answer is:
In our daily lives, we are constantly surrounded by sound—from the gentle hum of a refrigerator to the roar of a lawnmower. We have an intuitive understanding that some sounds are "louder" than others. But while physical sound intensity can be measured objectively in decibels (dB), loudness is a subjective psychological experience. A sound measured at 60 dB might seem quiet to one person and moderately loud to another, depending on the frequency and the listener’s hearing. To bridge this gap between the physical world of sound pressure and the human perception of loudness, scientists introduced the . Sones are subjective, derived from listening tests with

In the past, bathroom fans were loud by design—homeowners liked the "white noise" to mask other sounds. However, modern trends lean toward spa-like bathrooms.
