Many new headphones on the market are called "noise reducing" because they take sound waves that come in from the outside and add a sound wave to it that is exactly opposite (out of phase) to it; these add together to make no noise. What causes this?

• Refraction

• Absoprtion

• Diffraction

• Reflection

• Interference
