The architectural acoustical design of ultra high-rise building----take “Z15 Tower” as an example

摘要

The number of ultra high-rise building in China is growing fast in recent years, most ofthese buildings are high-grade commercial office buildings. This type of building usuallyrequires high demand of architectural acoustical design, mainly embodied in the complexand various acoustical design contents~1. The main architectural acoustical designs of theultra high-rise building include: the design of the sound isolation in buildings, buildingnoise control, the sound absorption design for special rooms~2, etc. “Z15 Tower” is an underbuiltultra high-rise building in Beijing whose owner is CHINA CITIC BANK. The heightof “Z15 Tower” is 528 meters and it will be the highest building in Beijing after itscompletion. The aim of this study is mainly to conclude the key points of the architecturalacoustical design work of ultra high-rise building by participating the actual architecturalacoustic design of “Z15 Tower”, and to find out the special acoustical designs in “Z15Tower” compared with other buildings which have normal heights.
