‘An intermittent hum, in windy weather, is believed to emanate from the roof’s glass blade which was first reported in May 2006 - just weeks after the tower opened. It is close to standard musical pitch of B3 (247 Hertz) and has been compared to a “UFO landing.” Work to reduce or eradicate the noise took place in 2007, 2008 and 2010. Foam pads were installed in 2007, aluminium nosing in 2007 and further work done in February 2010, but attempts to eradicate the noise permanently have been unsuccessful. In January 2012 strong winds caused very loud humming and the architect apologised. It was suggested that the decorative glass blade could be removed to solve the problem.’
“The simple and elegant form of the gate performs naturally as an enhanced acoustical device. Sound from the inside of the Nature Gate, like the cascading fall of water, is projected into the Jiajing Riverside Park. And conversely, like an ear, the Nature Gate amplifies the sounds of the external environment for those standing inside of the gate.”
‘Due to poor acoustics, students in classrooms miss 50 percent of what their teachers say and patients in hospitals have trouble sleeping because they continually feel stressed. Julian Treasure sounds a call to action for designers to pay attention to the “invisible architecture” of sound.’
