Have you ever experienced a loud noise while playing a game? Have you ever been trying to listen to music and felt a huge bump on your head? Have you ever thought that you might be a little bit deaf? Don't worry. This problem won't happen to you.

Let me explain. Most audio software comes with a built-in amplifier and a volume control. The audio software will detect the sound of your device and adjust the volume accordingly.

When you play games, for example, if you have a PC or a Mac, it will be adjusted automatically by the sound card. And if you have a smartphone, it's adjusted by the smartphone's own audio output. But there are also several games that don't adjust the volume.
