He developed an important formula for measuring a room's reverberation time.C. He renewed architects' interest in ancient theaters.D. He provided support for using established architectural principles in the design of concert halls.

Answer 1

Professor: But it was not until the beginning of the twentieth century that architectural acoustics became a scientific field. That was when the physicist Wallace Sabine started to do extensive studies on reverberation. 直到20世纪，Wallace Sabine 开始对混响进行大量的研究，建筑声学才成为一门科学领域。由此可知Sabine 是建筑声学领域的创始人，A 选项正确。Professor: The time it takes for the reverberant sound to die down is important for the acoustic quality of a room. Sabine recognized this and he came up with an equation to measure a room’s reverberation time. 大意为：混响时间对于房间声音质量很重要，而 Sabine 提出了一个测量这一重要时间的公式。B 选项正确，important formula对应原文important for the acoustic quality of a room。
