Why does people talking help me concentrate?

Lately I've noticed myself concentrating on a certain task when people are talking around me. I'm all over the place when I work alone and I seem to get distracted by everything. I'm not sure if its just me subconsciously trying to focus on a task or if its just the calm feeling of people around me. I tried looking this up in different place, but I keep getting opposite answers :/ mind explaining why this happens to me and/or tell me where I can find some audio of people talking(or a classroom lesson)?
P.s. active classrooms with students and teachers talking are probably the time I'm most attentive :/ I go to an online school now so this is a big problem for me XD
Thanks a plenty.
