IELTS SORU VE CEVAPLARI



Long ago churches were built in such a way that echoes were removed through holes in the walls. Every hole was the mouth of a juglike receptacle hidden within the wall. Every jug was by nature tuned to a characteristic wavelength of! sound an would, if left empty, spontaneously 1 emit that -sound in the presence of an identical solrndyBut if a certain amount of ashes was poured inn/the jug, the ash would absorb reverberationS/alAthe jug's characteristic frequency and convert the energy of the sound waves into heat, which would\quickly dissipate within the walls. Architectural refinements obviously inspiVed by the medieval "sound pots" < can be seen in many places today. Instead of/individual jugs in the walls, concert halls and/theaters have panels of hardwood screen. Sound enters the holes in the screen and spreads out/ in the space behind. The space is filled with blankets of rock wool, which replicate the silencing effect of the ancient jugs. Another sound-swallowing technique employs vertical wooden slats several inches apart. Reverberations enter the spaces between the slats and again encounter rock-wool mufflers. Aircraft designers have come to appreciate the potential of sound pots. The DC-10, first flying in 1971, was quieter than its immediate ancestors. The inner surfaces of the engine nacelles, the enclosed parts in which the jet airliner's engines ride, are perforated with hundreds of holes much smaller than the apertures in the church wall. Hidden behind these punctures, in a glass-fibered labyrinth sandwiched between metal sheets, are infinite miniature replicas of the ancient sound-swallowing jugs.   Mark the best choice         1.   The purpose of the medieval sound pots was to __________.
