This document analyzes the acoustics of a canteen recording. It notes that most of the materials in the recording space, like wood chairs and floors, absorb sound rather than reflect it. It also explains that background noises from many people talking and moving chairs are louder than the target speaker Sam due to both greater numbers of sound sources and glass surfaces reflecting voices. Movement of chairs also creates loud screeching noises that obscure Sam's speech.

A lot of the surroundings in this recording are wood meaning that they would absorb more than
reflect the sound so it has no reflection. In this recording there is a lot of people talking which is why
it is harder to hear Sam speaking this is all background noise and two reasons why they could sound
louder than Sam is that there is more of them and there is a lot of glass reflecting their voices.
People are also moving around and moving chairs which makes a loud screeching sound, this is also
louder than Sam speaking.
