When sound waves travel into the human ear, they face a few bumps along the way:

1. Complex Structure: The ear has three parts: the outer ear, the middle ear, and the inner ear. This makes it harder for sound to travel smoothly.

2. Sound Change: Sound waves have a tough time moving from the air into the thicker liquids of the inner ear. This can cause some sound energy to get lost.

3. Hearing Loss: If something damages the ear, it can change how we hear sounds.

Solutions:

• Hearing Aids: These devices make sounds louder for better listening.
• Education: Learning about ear health can help keep our ears safe from harm.
