Why do we lose hearing while yawning?

1. Muscles around middle ear contracts
2. Muscles around middle ear expands
3. Muscles around inner ear contracts
4. Muscles around inner ear expands

Correct answer: Muscles around middle ear contracts

Solution

During yawning, muscles in the middle ear contract and momentarily change how the ossicles transmit vibrations. This can make hearing seem muffled until the ear pressure and mechanics return to normal.
