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.
Ha elkezdenék hegedülni, hangmezőt generálnék, amely szétterjedne ebben a teremben, egy ponton az oldalfalaknak ütközne, és szétszóródna a teremben mindenfelé.
