20世纪60年代末，萨姆·沃纳梅克在伦敦发起了一项重建工程，该剧院是世纪末为威廉·莎士比亚剧团建造的。剧院以传统的方式建造，以忠实于幸存的文件所允许的原始风格，并有一个带开放式屋顶的圆形礼堂。剧院于1997年夏季开放演出。对剧院进行了声学测量。测量了剧院观众厅内的混响时间（RT）、早期衰减时间（EDT）、清晰度指数（C50）、清晰度（D50）和快速语音传输指数（RASTI）。在与声音教练和剧院演员协商后，选择了舞台上的各种源位置，并选择了接收器位置，以提供所有主要观众区域的统一覆盖。这些测量的结果表明，尽管剧院是露天建筑，但提供给大多数观众区域的早期能量的量导致了合理的语音清晰度水平，尽管实现足够的语音声级是一个更大的问题。剧院的露天设计以及它位于伦敦市中心通往伦敦希思罗机场的主要飞行路线之下的位置显然加剧了这一点。观众厅的混响特性一般在现代剧院可接受的范围内。
In the late 1960’s, Sam Wanamaker initiated the reconstruction in London of the theatre built for William Shakespeare’s company of players in the late 16th century. The theatre was built in the traditional manner to be as faithful to the original as surviving documentation allows, and has a circular auditorium with an open roof. The theatre was opened for performances in the summer of 1997. An acoustic survey of the theatre has been carried out. Measurements have been made of reverberation time (RT), early decay time (EDT), clarity index (C50), definition (D50), and rapid speech transmission index (RASTI) within the theatre’s auditorium. Various source positions were chosen on the stage after consultation with voice coaches and actors at the theatre, and receiver positions were chosen to provide uniform coverage of all the major audience areas. The results of these measurements indicate that, despite the theatre’s open‐air construction, the amount of early energy provided to most audience areas results in reasonable levels of speech intelligibility, although achieving an adequate speech sound level is more of a problem. This is clearly exacerbated by the theatre’s open‐air design, and its position in central London under the main flight path to London’s Heathrow Airport. The reverberant characteristics of the auditorium are generally within acceptable limits for modern theatres.
