Your mission today, should you choose to accept it, is to go out side and find a wooded area. It doesn't have to be heavily wooded just a few trees is fine. Then stand there, or sit if that is more convenient. And listen.
I prescribe at least one half an hour, or the full hour if you're ambitious, but I understand how busy you are so even if you can only manage a few minutes it will be worth your time.
Thank you and have a nice day.
