Because foam moulds itself to the contours of your ears and or the inside of the defender therefore stops sound waves from entering.It also absorbs sound.If you increased the sound you would have to increase the thickness or density of the foam.Foam is used on car insulation as well for the same reason.It deadens vibrations.

Why is foam a good ear defender?
foam would be a good material to use for the inside of the ear defenders, as it will give more support, as well as being dense to conduct sound. Foam has particles with several small air particles, forming sound waves to absorb into it's surface.
What is the material used for the soles of shoes?
The material commonly used for shoe soles is rubber, as it provides good traction and durability. Other materials, such as leather, foam, and synthetic compounds, are also used depending on the shoe's intended use and design. The choice of sole material can impact the shoe's comfort, flexibility, and longevity.
Best shock absorbers?
rubber is one of them i would say foam but rubber is good
What material are on the sides of ear defenders made from?
because it is the best material because it absorbs the sound the best, it is also dense so it can conduct sound. Foam has particles with several small air particles, forming sound waves to absorb into its surface.
Is foam rubber a good insulator?
Foam rubber can be a good insulator due to its cellular structure that traps air pockets, providing thermal insulation. It also has good sound insulation properties, making it useful in dampening noise. However, its insulating effectiveness can vary depending on the specific type and density of the foam rubber.
Why is a foam box a good insulator?
Foam is made of material that a very low level of confuctivity
Is a foam box a good insulator?

What is a good material to filling the ear defender?
foam and plistyreine
What material are ear plugs usually made from?
You should use foam because foam molds itself to the contours of your ears and or the inside of the defender therefore stops sound waves from entering. It also absorbs sound. If you increased the sound you would have to increase the thickness or density of the foam. Foam is used on car insulation as well for the same reason. It deadens vibrations.
What material is a good insulator against heat?
rubber
Is rubber a good material to stop floods?
yes
What is a good example of an insulator you can find at home?
mugs,foam cups and plastic cups
