The document discusses three acoustic concepts - Refraction, Echo and Diffraction - as depicted in an image, with Reflection and Diffraction being observed when recording sound in an enclosed toilet space with little room for sound to travel except through reflection and diffraction.

1. The acoustics’ of pitch and frequency throughout the recording and the image above really describes the
concept of Refraction, Echo and Diffraction. As the three sound effects are clearly seen and depicted above.
When recording in the toilet we noticed that it was really enclosed and that there wasn’t much room for the
acoustic sound to travel. The sound defiantly travelled but mainly through Reflection and Diffraction. The image
above mainly a easy example of Diffraction and Reflection.
