Diffraction Definition - What is Diffraction?

Diffraction is a physics term that means sound waves coming from audio source are spread out as a result of passing through a narrow or small opening. This can be seen in audio when waves hit a building or are blocked by something with the power to do that. The wave is lost or is sent in a different direction. From a practical standpoint audio diffraction can be seen in real world examples like a large fence blocking traffic noise or a large dirt area around a loud venue like a concert hall or a race track. Those are real life examples of audio diffraction.
