Amplifiers - Linear/Logarithmic Volume Control. Human perception of loudness is logarithmic, not linear, and as such, some volume controls cater to the human ear using logarithmic potentiometers. In linear potentiometers, the amount of …

It has been discovered that we perceive volume logarithmically with respect to sound intensity. This means that, to increase the volume of something by one Bel, the unit of audible sound (decibels are used more often; there are, of course, 10 …

low distortion logarithmic audio volume control with glitch reduction. The logarithmic taper is achieved by adding resistor R8 between the wiper connection and ground. This method is described in detail in the article “Tack a Log Taper onto a Digital Potentiometer” by Hank Zumbahlen, EDN, 1/20/00.

A Linear Logarithmic Volume Control - Audio and Political ...

Every 2 to 1 difference in sound level registers about the same change regardless of absolute level. Thus it is said that our hearing scale is logarithmic. A linear adjustment used alone would only allow about 20dB of useful adjustment in its through most of its range, the rest of the lower level crowded at the bottom of the adjustment as shown in figure 1 .

Once shown the difference they are converts (I've seen this multiple times). It's an incredibly easy (one line) fix that will make your controls feel significantly nicer and more usable. volume = Mathf.Pow (volume, 2f) You can scale the power up to 3f, 4f+ for different curves.
Why should I use a logarithmic pot for audio applications?
https://electronics.stackexchange.com/questions/101191/why-should-i-use-a-logarithmic-pot-for-audio-applications
However, the fact is that a sound wave must have 10 times the power of another to sound twice as loud. How does the log changes in the pot resistence relates to sound waves and how the human ear works? Assume the potentiometer (volume control) varies the signal power applied to the loudspeaker and assume the amplifier can produce a maximum of 100W.

The decibel (dB) system of sound intensity is a measure of how loud a sound is to one's ears. It is represented by the equation It is represented by the equation [math]dB=10 \times log_{10}(\frac{I}{I_o})[/math]

Being in an environment with 0 dB(A) is actually a weird experience. The loudest volume level (the ‘pain threshold’) is about 120 dB(A). A classical orchestra can produce about 94 dB(A). Note that because of the logarithm, multiplying the power of a sound by a factor of 10 means adding 10 to the dB(A) value.
