Acoustics Plus were contracted by the communications company working on Network Rail’s £500 million redevelopment of King’s Cross to design and test a new public address and voice alarm system.
King’s Cross station is one of the busiest in the UK and struggles to cope with its 40 million-plus passengers a year – a figure set to increase. The redevelopment will address this problem, transforming the entire station by 2013. By the time of the 2012 Olympics, there will be a new concourse and an improved interchange with St Pancras International.
Design the public address and voice alarm system for the new western concourse, train platforms, and train sheds
Carry out an acoustic computer modelling study to verify that the proposed acoustic design will meet the acoustic design criteria specified in the performance constraints
Parameter prediction including reverberation time, sound pressure level and speech transmission index
Post commissioning electro-acoustic performance assessment of intelligibility and sound pressure level.
The acoustic design had to work within constraints dictated by the listed status of buildings at King’s Cross Station.
PA-voice alarm system for new western concourse scheduled to be installed by 2012.
