I always took out my earphones or turned down/off speakers while doing computer modifications. I want to hear things like that fans are spinning, how busy the hard drive is if the screen is not yet working... in a computer repair shop I noticed others didn't do the same and that's when I realized that I was subconsciously doing this in the first place. Nowadays I do less of that messing around, but also there's SSDs and quiet laptops. Either way, yeah I totally get you.
