How is Volume Attenuation Calculated for 3D Sounds?

Hello,

I am trying to create a function where I can basically get the estimated volume of a 3D sound in the environment at a certain position, which takes into account the so-called "volume attenuation". The Sound Instance has many properties that can affect this calculation, such as the Sound.EmitterSize, Sound.RollOffMode, etc. However, I can't seem to find any resource, Roblox related and non-Roblox related, that showed any equation and its variables/calculations. The Roblox Developer Hub only tells you very little about the variables used, but not anything else.

Thanks!
