Sound usually travels through which medium to reach our ears?

Options

A. Air
B. Water
C. Wood
D. Asbestos

Explanation

**Step-by-Step Solution:**

1. **Understanding Sound Transmission**: Sound is a mechanical wave that requires a medium to travel. It cannot travel through a vacuum.

2. **Identifying the Medium**: The most common medium through which sound travels is air. This is because air is the surrounding medium we are usually in when we hear sounds.

3. **How Sound Travels**: When a sound source (like a person speaking or a musical instrument) vibrates, it creates disturbances in the air particles around it. These vibrations cause the air particles to move, creating a wave of sound that travels through the air.

4. **Reaching Our Ears**: As the sound wave travels through the air, it eventually reaches our ears. The ear detects these sound waves, and the brain interprets them as sound.

5. **Conclusion**: Therefore, the answer to the question is that sound usually travels through air to reach our ears.
