This sounds like an XY problem. What you want is for your ears to not be hurt by loud sounds. Physical audio kill switches is one solution but I can think of many others that I personally would prefer. One thing that comes to mind is a system that monitors the audio output and keeps that from exceeding some predefined maximum.
