Listening is not the same as hearing. Hearing refers to the sounds that enter your ears. It is a physical process that happens on its own.
Listening is the ability to accurately receive and interpret messages in the communication process. A good listener will listen not only to what is being said but also to what is left untold or only partially said.
Therefore, effective listening involves observing body language and noticing discrepancies between verbal and non-verbal messages, as well as what is being said at any given time.
So listening is not only a matter of using your ears but the eyes as well.
