Especially for aural learners, studying with music or some kind of background noise is essential, but you're kind of walking a fine line between helping you study and distracting you. Personally, I like really like to study in a cafe because of the background noise, or some instrumental music. Here is a list of websites to help you concentrate!
i can't say how much i love this site! it's basically a place where you can find different ambient mixes that people have made by taking different sounds and combining them. my go-tos are:
coffitivity is a website that has different cafe noises. there are three that aren't premium: morning murmur, lunchtime lounge, and university undertones. with premium (9 dollars) you get three more: paris paradise, brasil bistro, and texas teahouse. though if you are looking for those, you can find similar mixes on ambient mixer for free.
happy studying! if you have any other websites or apps, let me know in the comments!
