I'm the same way. My partner is able to do all her homework while listening to music or playing a show in the background. I was somewhat envious, until I looked at some studies that suggest while it's possible, it's not ideal, and can reduce information retention.
As to why some people have an easier time doing it than others, no clue. I have a background in music so I suspect that plays some role. I need absolute silence in order to concentrate.
