The document discusses how soundwaves are absorbed differently inside a canteen versus outside. In the canteen, ambient sounds from other people speaking and moving chairs absorb the soundwaves, making speech low pitch and hard to hear in recordings. Outside, there are no other sounds to absorb the soundwaves since it is an open space without a roof, so speech is clearer to hear.
