**Step-by-Step Text Solution:**

1. **Identify the Basic Functions of the Ear**: The ear has two primary functions that are essential for human interaction with the environment.

These vibrations are then transmitted to the inner ear, where they are converted into electrical signals that are sent to the brain. This process allows us to perceive sounds.
