Tarik puts his head down on a desk after he's done taking his quiz. When Mahi (who's sitting next to Tarik) goes to stand up to get a tissue, his desk accidentally bumps into Tarik's desk making a small noise. Tarik jerks his head off the table and when the teacher comes over to see to the disruption, he says that the bumping sounded REALLY LOUD when his head was down. How could you use science to expain why the noise was louder to Tarik, with his head on the table, than it was to the other students that did NOT have their heads down. (hint: assume proximity--how close or far students were--to Mahi does not matter)
