I've actually done this thing, as in I've participated in a 10-day Vipassana meditation course, during which participants cannot listen to music or interact with each other.

I can say that forcing silence upon myself resulted in a "mental withdrawal", if you will. It wasn't very pleasant, the music gets louder and louder and quite unbearable at times. That said, I did indeed see some effects at the end, in a form of periods of silence in my mind(which was kind of spectacular for me; there's some music in the back of my head at all times). My opinion is that even longer period of non-listening would yield even bigger results.

I really recommend the experience(the deprivation, I mean; the Vipassana part is also cool, but kind of orthogonal). Even though it's very demanding, you can really put things into perspective and learn a lot about how your body reacts to things. It also gives you a completely different outlook on stuff like solitary confinement.

What do you mean force silence upon myself? Are we talking meditation or just working/reading in quiet places? For minutes or hours (or days)? I first noticed the music thing when I was on the high school swim team and would swim for multiple hours every day. Under water it's not quiet, but there are no discernible sounds beyond the water itself--all I would hear was the music in my head.

I don't mean to sound like I'm complaining. I love music and it's been a huge part of my life since I can remember (and I'm old).

But from my experience, I don't buy your theory. I think I'm just wired different than people that seek out quiet places.

Force silence upon oneself is to shut up the mind as soon as it starts blabbering. There are means to ease this up, like counting or looking at things and focusing on their characteristics (green jacket, yellow leave, noisy car) or feeling your body (my thumb tickles, my stomach feels empty).

Just stop when the brain starts picking up from there: "My stomach feels empty (BECAUSE YOU HAVEN'T EATEN AND WHENEVER YOU DO YOU EAT TRASH)" you just stop the thought on the BE and focus on the next inner or outer thing or on the next number of the count. When you can't stop the thought on time, just ignore it and move on.

At first is hard, especially with a noisy brain, but it gets easier and easier.
