Music studios use “soundproof" recording rooms. The walls of these rooms are designed in such a way that the only sounds that reach the microphones inside the room are sounds from inside the room. The most important characteristic in designing the soundproof room is to create walls that–
allow sounds to move easily from one place to another
reflect sounds around the room to alter their properties.
absorb sounds and prevent them from passing through.
allow communication between people inside and outside the room.
What does the speed of sound depend on?
the type of wave
the medium
law of reflection
transmission

Sound waves are absorbed by dense solids and reflect off liquids.
Sound waves can travel through and reflect off rock layers.
Sound waves require energy, such as electricity to generate them.
