Doors of the 'quietest room in the world' have been thrown open to allow scientists to study nanotechnology in Bristol, UK.
The architecture of the 11-million pound laboratory, that virtually has no air movement, keeps echo and sound waves from penetrating the building designed by architects Willmott Dixon South West and Wales.
The "'ultra-low vibration suite" in the city's Nanoscience and Quantum Information Centre, University of Bristol, will be used by researchers for a string of experiments.
"Due to the stringent and exacting nature of nanoscience, the new facility had to meet the most detailed constraints for vibration and acoustics," the Telegraph quoted Managing director Neal Stephens as saying.
"An extremely controlled environment is paramount with almost zero vibration, acoustic and air movements. The demands, therefore, for quality in construction and delivery were second-to-none.
"We anticipate that this state-of-the-art facility will attract very considerable interest, not only from scientists but also those keen to learn more about the unique challenges faced by the construction team and the ways in which they were overcome," Stephens added.
Architect Iain Martin, who also worked on the building, said: Although technically complex, it has exceeded expectations by becoming 'the quietist building in the world' in terms of vibration performance.
"For the scientists, it is a beautiful building for this reason alone."
