Human hearing is logarithmic. A 3db increase in volume is barely perceptible to us. This means that if you double the volume, it is just about noticeable to us.Just about everyone but Youtube understands this. The Windows, Android, Mac, iPhone volume controls all utilize a logarithmic scale for volume control, which means that the steps are fine-grained and consistent.Youtube on the other hand insists on using a linear scale. If you use keyboard controls, the range from 50-100% only increases the perceived volume a little bit, while the steps from 0-5%, and 5-10% are too coarse to be useful. So I give up and just use the device volume controls instead. Trying to use the mouse is equally challenging, where even pixel level movements sometimes result in a drastic change in volume.I had reported this as a suggestion a few years ago, but for a company that chooses not to respond to celebrities losing their Google accounts, you can guess where the suggestion was dumped. I just hope someone at Youtube sees this and finally fixes the issue!
