Is "listen to" same as "hear?"

No, "listen" isn't the same as "hear!" "Listening" is intentional, whereas "hearing" is something that happens without any effort. Ex: I heard the phone ringing, so I went to pick it up. Ex: I was listening to your song last night. I really like the lyrics. Ex: I can't hear anything since I have noise-blocking headphones.
