We use 'hear' to mean simply that sounds come into our ears. It may not be deliberate. As soon as we wake up and walk around, we hear things. Example : - I heard a knock at the door. - I suddenly heard a loud noise. - Can you speak louder please? I can't hear you.
Hear is NOT used in a continuous tense. Instead, use can hear, example: - I can hear you! ( NOT I am hearing you) - I couldn’t hear you! ( NOT I am not hearing you)
Listen (to) (mendengarkan)
When we listen, we try to hear. We pay attention and try to understand every sound. Example : - Listen! Is someone crying? - Listen to this song. Can you understand the words? - I'm listening but I can't hear anything.
When we use 'listen' with an object, we say : listen + to + object, for example: John is listening to the radio.
