The perceived loudness change of a change in volume depends on the listening volume: at high volumes a 1 dB increment is noticeable, but at low volumes a larger increment is needed to get a comparable change in loudness. Perceptual volume adjustment accounts for this fact, and divides the hardware volume range into a number of steps. Each step changes the dB volume by a variable amount, with most of the steps concentrated at higher volumes. This makes it possible to sweep over the entire hardware volume range quickly, without losing the ability to finely adjust the volume at normal listening levels. Use "Volume Adjustment Mode" in the system settings menu to select perceptual volume mode. The number of steps used is controlled by "Number of Volume Steps". (Number of steps has no effect in direct adjustment mode.) It's still possible to set a specific dB volume level from the sound settings menu when perceptual volume is enabled, and perceptual volume does not affect the volume displayed by themes.
