To draw a particle diagram that shows how ear defenders work, you first need to understand the basic functioning of these devices. Ear defenders, also known as earmuffs or hearing protectors, are designed to reduce the intensity of sound that reaches the ears by creating a physical barrier between the sound source and the ears.

Here's a step-by-step guide on how to draw a particle diagram demonstrating how ear defenders work:

1. Start by drawing a horizontal line to represent the surface or environment where the sound is present.

2. Next, draw a speaker or sound source, represented by a small circle or square, along the horizontal line. Label it as "Sound Source."

3. Above the sound source, draw a person's ear on each side of the line. You can draw simplified ear shapes, resembling oval or mushroom-like structures. Label them as "Ear."

4. Now, draw a large rectangular shape around each ear, representing the ear defenders or earmuffs. Both rectangular shapes must intersect with the ears, completely covering them. Label them as "Ear Defenders."

5. To indicate that sound waves are being blocked, draw small squiggly lines entering the ear defenders from the sound source but not reaching the ears. These squiggly lines represent sound waves.

6. Optionally, you can draw arrow-like lines on the outside surface of the ear defenders, representing sound waves bouncing off or deflecting away from the ear defenders.

7. You can also add extra details, such as headbands or fasteners, to enhance the realism of the particle diagram.

Remember, the primary purpose of the diagram is to demonstrate how the ear defenders create a barrier, preventing sound waves from reaching the ears.

Note: A particle diagram is a representation of particles or objects in a system. In the case of ear defenders, the particles being depicted are sound waves.
