Even as a native English speaker I experience this from time to time.
I'll idly hear someone speaking - usually at quite some distance - but their words are very indistinct, I'm unable to make out what they're saying. I'll think to myself "what language are they speaking?", but after a second or two, there's some kind of frequency tuner in my brain that settles on the correct band and suddenly everything falls into place and I can understand them perfectly.
