Because it absorbs the sound but not all of the sound. :)
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.
Cardboard is not a good insulator compared to other materials like fiberglass or foam. It can provide some insulation, but it is not as effective at trapping heat or blocking sound as other materials designed for insulation.
Air is the worst sound insulator as it allows sound waves to pass through easily. Materials like foam, fiberglass, or mass-loaded vinyl are better options for soundproofing.
Foam is not a good conductor of sound due to its ability to absorb and dampen sound waves. This property makes foam a popular material for soundproofing and noise reduction in various applications, such as studios, theaters, and cars.
Yes, wool is a good sound insulator because it has natural properties that absorb sound waves and reduce echoes. It is often used in soundproofing applications for its ability to dampen noise.
paper or foam cups
insulator
is foam dirt an metal a good insulator
A vacuum is a great sound insulator. Materials that absorb energy such as wool are good insulators as well. I heard of a silicone adhesive that transformed acoustic energies into heat - that was a good insulator if it was used to glue two sheets of something together.
cuz it has a lot of air particles in between which allows the sound to travel slower.

Foam is made of material that a very low level of confuctivity

of course beause it is a type of foam
Styrofoam, along with most other expanded plastics, is a very poor insulator of heat and electricity, thereby making a foam coffee cup a very good insulator.
