There are plenty of activities these days which require specific enviroment conditions like silence. (Or you could just simply say, "activities that require silence")

If you are trying to focus on something/concentrate on something, silence is a crucial thing/a quiet enviroment is a crucial thing. (the reason I didn't include the second half of that sentence is because you were technically saying the same thing twice :) and the second part wasn't needed but you may also change this sentence a lot of ways) 

(You might not want to use the phrase 'on the other hand' in this scenario but I'll leave it anyway)

On the other hand, noise is a distraction. (This is how a typical english speaker would phrase this, but if you wanted you could say: On the other hand, the noise ruins creative thinking and concentration) (though, you were using the word 'diffuse' in a way that makes sense, it is not a good place for it in your example in my opinion. :) )

with positive thinking, I have come up with a solution for my struggle and bought a headset. Though, I don't listen to any music, I just put them on and block out/cancel out the noise.

(Sorry if I changed it too much, there are a lot more ways you can write this, I just gave you a couple options)

Keep up the good work :)
