Example:
Imagine you're standing outside a house and trying to hear a conversation happening inside. Just like how a window transmits the sounds from inside the house to you standing outside, the eardrum acts as a barrier that conveys sound vibrations from the outer ear to the middle ear. In this analogy, the window represents the eardrum, as both serve as a medium that allows sound to pass through, enabling you to hear the conversation—whether it's happening inside a house or inside your ear.
