Take for example the Lincoln Center in the United States. Its sound system was torn down and rebuilt six times before it was improved. Likewise, the Sydney Opera House in Australia closed for renovations which took ten years to complete.
例如美國的林肯中心為了改善音響效果，拆改了六次；而澳洲的雪梨歌劇院也曾因演出效果不良，封館整修了十年，才達到今日斐聲國際的水準。
