The difference between hearing and listening is that hearing is the process of taking in noise and sound, whereas listening is when an individual tries to understand what they are hearing. Hence, listening is different from hearing because it requires more conscious action.
The main difference between hearing and listening is the amount of attention put into it. Hearing simply happens, whereas listening requires concentration and effort. Human beings can hear sounds much faster than they can process thoughts. In a world with so many different background noises, humans have developed the ability to block out certain sounds and only focus on certain things.
