Why is foam a good ear defender?

Foam is a good ear defender because it:

- Softens the impact of sound waves: Foam ear defenders are made of a soft, pliable material that helps to absorb and soften the impact of sound waves, reducing the amount of noise that reaches the ear.

- Conforms to the shape of the ear: Foam ear defenders are designed to conform to the shape of the ear, creating a snug seal that helps to block out noise.

- Lightweight: Foam ear defenders are lightweight and comfortable to wear, making them ideal for long periods of use.
