If I would start to play the violin, I would generate a sound field which would propagate in this hall, and at some point, the sound field would hit the side walls and would be scattered all over the place.
Se eu começasse a tocar violino, eu criaria um campo de som que se iria propagar neste corredor, e a algum momento, o campo de som iria atingir as paredes laterais e espalhar-se-ia ao longo deste espaço.
