Improving Livability by Controlling Structural Noise Annoyance Inside Apartment Towers

Residents at a number of tall apartment towers complain of noise annoyance emanating from the internal cold-formed steel wall structures during high wind events. The objective of this presentation was to establish common attributes among problematic buildings and to investigate the root cause of the problem. Many factors of skyscraper designs are considered and debated in the research, including building shape, wind speeds, vortex shedding, urban density, decreasing build times, concrete formwork methodologies, curtain wall designs, internal wall partitions and ceiling systems, and resident expectations. This presentation included a case study of a recently completed, 250-meter-tall building that experienced significant noise inside the wall cavity. A number of remedial treatments were administered to the internal cold-formed steel structures, including demolishing walls and rebuilding them with entirely new, never-before-seen building innovations. Conclusive evidence suggests that, although skyscraper infrastructure has changed dramatically over the last 50 years, the way we build our internal wall structures has not, and it is to the detriment of the very inhabitants these buildings are supposed to accommodate.
