Logarithmic Addition of Sound Levels In order to determine the resultant sound pressure level (SPL) of multiple sources the SPLs must be added logarithmically. This calculation assumes that the SPL of each source running in isolation is known at a given measurement point.
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
Sound level is measured in dB and, a 10 dB increase/decrease in signal equates to a doubling/halving of loudness as perceived by the ear/brain. Look at the picture above and ask yourself which is the better choice for smooth (coupled with extensive) volume controller.

This function uses the range from 0.0 to 1.0 regarding to the MSDN documentation so you don't need to implement a logarithmic function yourself. Seems like I overlooked this one. Here's the current code sample I am using in case someone will need it in the future.

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 resistance changes in a direct pattern. If you turn or slide it halfway, its resistance will be halfway between its minimum and maximum settings. That's ideal for controlling lights or a fan, but not …

Sound - The way sound is picked up by one's ears is of logarithmic nature. 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 d B = 10 × l o g 10 ( I I o) where I o is the threshold of hearing and I …

46-65 dB: If you’re walking down the road in a little city, this is around the decibel level of the noise you’d hear. Standard conversation, the sound of a bubbling flow, along with also the meow of your kitty may generate sound that drops from the 45-65 decibel range.
