A lot of people think listening and hearing are the same thing, and even though you use your ears for both, they are actually very different. When you hear someone, that is all you are doing, but when you are listening, you are actually understanding what they are saying and hopefully connecting with it. There would honestly probably be less issues in the world if we listened to each other instead of just hearing what we want. You are able to academically connect with your work, professors, and classmates. You are able to listen to feedback, criticism, and hints on how to do better on tests or assignments. You can also have personal benefits from listening to each other instead of just hearing each other. You are able to complete the communication loop, where one is the receiver and the other is the giver. Hearing breaks that loop and listening keeps it going around.
To show you are listening you need to do three things. You need to show that you are paying attention. I struggle with this personally because even if it seems like I am not paying attention, I really am and it catches people off guard most times. The next thing you need is the right attitude. If you are having a political debate with someone, you cannot just yell at each other, neither of you would be listening to each other. You have to remain calm, but you can still be very passionate about your views while staying calm and not letting your emotions control. The final thing you need to do is adjust. If someone has a different view from you, temporarily change the way you are looking at the world to how they see it and you would be able to understand and listen to them better instead of just hearing them.
When you are the listener, you need to make sure that you show you are listening. Whether it is verbal feedback or nonverbal. It could really help the speaker. You can always say whether you agree or disagree and why, and you can always nod your head in agreement or lean forward to show that you are interested in the conversation instead of leaning back in your chair or leaning on your hand, it might discourage the speaker.
