The small closed interior area with plastic boards on the walls and lino flooring would reflect sound, making it louder, while a few people and wooden doors with glass windows would absorb some of the sound. Brick walls in other areas would absorb projected sound.

This is a small closed interior area so there isn’t far for the sound to travel therefore the sound
should be louder than the sound in the canteen. There were a few people in the corridor so they also
absorb some of the sound. Also there are wooden doors with glass windows not only absorb but also
reflect the sound.
