问题     The physicist Wallace Sabine pioneered the scientific study of architectural acoustics when he was asked in 1895 to fix a university lecture hall in which the echo of a speaker’s words rendered them unintelligible. He found that the length of time it takes a sound’s echo to decay is determined by the absorption of the sound’s original energy by surrounding material. By hanging panels of sound-absorbing felt on the walls, Sabine reduced the echo enough to make the hall usable. And the data he compiled yielded a mathematical formula for the relationship between a room’s echo duration, its quantity and quality of sound-absorbing materials, and its spatial volume.
The passage suggests that Sabine’s work made which of the following possible for the first time?
选项 A、to make a room soundproof
B、to build an auditorium out of sound-absorbing materials
C、to construct an enclosed space in which sound would not echo
D、to design a building to meet predetermined specifications with regard to echo duration
E、to render any large room usable for public lectures and performances
答案D
解析 根据第一句的pioneered可知，在这个大学报告厅项目中，萨宾所做出的所有成果都可以被认为是史无前例的。根据文章，萨宾的研究结果之一便是确定了回声持续时间和吸收声音的材料以及空间之间的关系，而知道了这一点便可以建一间房子，可以满足特定的、人们想要的回声持续时间，所以选项D正确。A项文中未提及。B项从文中无法得知使用吸收声音的材料建造礼堂是不是有史以来第一次。C项文中未提及。E项太极端。而且文章未提及如何让房间适合performances。
