建筑声学(国外英文资料) Architectural acoustics is the science of studying acoustic environmental problems in buildings. It mainly studies indoor acoustics and noise control in building environment. Records of architectural acoustics first appeared in the first Century BC, and were written by the architect Vitrurius of Rome, the ten books of architecture. The book describes the methods of sound conditioning in ancient Greek theaters, such as the use of resonant cylinders and reflectors to increase the volume of a play. In the middle ages, European churches used large internal spaces and walls with low sound absorption coefficient to produce growth and noise, which created a mysterious religious atmosphere. Resonators used to absorb low-frequency sound were also used to improve the theaters sound effects. From 15 to seventeenth Century, some European theater building, there are mostly ring boxes and bench seating arrangement to close to the ceiling, at the same time, due to the absorption of sound energy and the audience dress, scattering the ornate interior and concave convex structures on the sound, the reverberation time is moderate, the field distribution is relatively uniform. The design of a theatre or other building may have been designed to solve the problem of sight, but it has made good sense by accident. In sixteenth Century, China built the famous Tiantan of Beijing, the dome of the sky, with a diameter of 65 meters of the echo wall, can make a faint sound along the wall spread one hundred or two hundred meters. Before the steps of the imperial vault, there are three stones that can be heard several times. In the 18~19 century, the development of natural science promoted the development of theoretical acoustics. By the end of the nineteenth Century, classical theoretical acoustics developed to the highest peak. At the beginning of twentieth Century, the United States put forward the famous theory of Sabine reverberation, the architectural acoustics into science cat
