Materials that are good reflectors of sound include:
Hard objects are the good reflectors of sound because particles bounce straight off them. If they are smooth, the sound reflects at the same angle it hit the surface and is not spread out.
The most commonly used materials that are effective for blocking sound include drywall, sound deadening fiberboard, mass loaded vinyl, insulation, and sound curtains. Dampening compound can also be used as the damping layer between layers of drywall, plywood, or sub-flooring.
Materials that stop sound are generally referred to soundproofing materials. Examples of these materials are resilient channels, rock wool insulators and acoustical mats.
If the sound wave is absorbed it will not be reflected. Sound absorbing foam have a lot of very small pores in which sound loses it's energy as it travels in the tiny tunnels.
Depends on the kind of sound source you are referring to.
These materials are called phonic insulation products.

a vacuum
Sound waves need a physical material to carry them, but electromagnetic waves don't.
the 'medium'
sound wave need material becuse sound wave formed by compresion and rarefaction
Sound waves are mechanical waves and all mechanical waves require a material medium for its propagation unlike electromagnectic waves
Sound travels by causing molecules in the material to vibrate parallel to the direction of motion. Sound waves are longitudinal waves.

sound waves
A simple answer from a simple man. Sound waves travel until they hit something solid and then bounce back. Carpet and curtains are not even solid surfaces where sound waves can bounce back from. If they (the sound waves), have nothing to bounce from they stop traveling. The material of the carpet and curtain actually redirects the sound waves throughout the material instead of coming back to you.
Sound creates waves in a material- compression waves. These waves are transmitted through the atoms/molecules in the material to the receiver. The denser a material is, the more effectively sound may travel; this is because the sound waves are transmitted more easily through the tightly packed molecules.
Because sound waves are mechanical vibrations of material matter. You can't have sound waves in a space where there's no material to vibrate.
Sound waves need a physical material to carry them, but electromagnetic waves don't.
Sound waves can travel through any compressible material (which means any real material), be it solid, liquid, or gas. Sound waves cannot travel through a vacuum.

Yes.
Yes, sound waves can be reflected fro liquids or gases that present a interface with another material or the same material of a different density.
