Why is foam rubber a good material for ear defenders?

Noise Reduction

Foam rubber is an effective material for ear defenders because it helps to reduce noise. It does this by blocking sound waves from entering the ear. The foam material absorbs the sound waves, preventing them from reaching the eardrum.

Comfort

Foam rubber is also a comfortable material to wear. It is soft and pliable, so it conforms to the shape of the ear. This makes it comfortable to wear for extended periods of time.

Durability

Foam rubber is also a durable material. It is resistant to wear and tear, so it can withstand being used over and over again.

Affordability

Foam rubber is also an affordable material. This makes it a cost-effective option for ear defenders.

In conclusion, foam rubber is a good material for ear defenders because it is effective at reducing noise, comfortable to wear, durable, and affordable.
