Sound is a waveform that travels through Sound is a waveform that travels through matter. Although it is commonly matter. Although it is commonly associated in air, sound will readily travel associated in air, sound will readily travel through many materials such as water and through many materials such as water and steel. Some insulating materials absorb steel. Some insulating materials absorb much of the sound waves, preventing the much of the sound waves, preventing the waves from penetrating the material.waves from penetrating the material.
