Any tips for learning audio cues?

ive been struggling on improving on defence i find myself rushing at the wrong times and not knowing cues and i cant really tell where anyone is, sometimes in fights i engage at bad times but i dont know when the good time to engage if it helps im a smoke main, and im also on ps4. thanks

I posted this on r/Rainbow6 sub reddit and got recommended this one so any tips? i am trying to get better i just need a few engage tips and audio cue tips, Thanks.
