: Measure the physical intensity or pressure of sound waves. Because the human ear is incredibly sensitive, decibels use a logarithmic scale. A 10 dB increase represents a tenfold increase in physical intensity, but only a doubling in perceived loudness.
A "sones" is a unit of measurement for loudness, specifically defined as a subjective measure of sound intensity.

Sones: Understanding How We Perceive Loudness A is a subjective unit of loudness that measures how humans actually experience the intensity of sound. Unlike decibels, which measure objective sound pressure, sones are designed to match the human ear's non-linear perception of volume. Core Definition
: Standard office or conversation noise level. : Measure the physical intensity or pressure of sound waves
The definition of a sone is: $$1 \text sone = 40 \text phon$$
: The sone scale is linear. This means that a sound rated at 2 sones is perceived as twice as loud as 1 sone , and 4 sones is twice as loud as 2 sones . A "sones" is a unit of measurement for
Technically, is equal to the loudness of a 1,000-hertz (Hz) tone at a sound pressure level of 40 decibels (dB) above the listener's hearing threshold.
To understand sones, it helps to understand . A phon is also a unit of perceived loudness, but it matches the decibel scale at 1,000 Hz. The relationship between the two is generally defined by the formula:
Understanding sones can save you from buying a fan that sounds like a jet engine—or one that’s so quiet you forget it’s on. Here’s everything you need to know.
