Its simple plastic is hollow and and sound waves usully bounce off of hollow things
Yes.
Ear defenders don't reflect sound waves, they absorb or reduce the amplitude of the sound.
The water will reflect some of the sound, and some will travel downward through the water.
If you can see it, then it does.
i think they reflect echo..... not too sure
Echo
no, because its plastic and ya
yes sound can travel through plastic but i also depends where the plastic is to see if it can reflect most of it
This much depends on the properties of the plastic. Foam will reflect little and absorb much. Hard plastic will reflect much and absorb little. Soft plastic will absorb more than hard plastic and reflect more than foam. Regards.
Plastic wil reflect the sund
All solids can reflect sound. Different plastics reflect by different amounts. Sound waves are vibrations. They transfer energy to the solid when they hit it, and the particles of solid vibrate more, and can transfer this vibration back to the air.
