Hearing is one of your five senses: the ability to perceive sound through your ears. When someone speaks, plays music, or drops a book, vibrations travel through the air as sound waves. Your ears catch these waves and your brain interprets them, letting you understand words, enjoy melodies, or recognize the crash of something falling.

The word also refers to a formal meeting where evidence or arguments are presented. In a court hearing, a judge listens to both sides of a case before making a decision. A school might hold a hearing before deciding whether to expel a student, giving everyone involved a chance to explain what happened. Congressional hearings let lawmakers question witnesses and gather information about important issues. The key idea is that people in authority are listening to what others have to say before making an important decision.

When someone has good hearing, they can detect quiet sounds and distinguish between similar noises. Some people lose their hearing partially or completely due to age, injury, or genetics, which is why many learn sign language or use hearing aids. Musicians and sound engineers often develop exceptionally sharp hearing through years of careful listening.
