The Science Behind Good Acoustics


The new workspace at AstraZeneca UK’s head office in Kings Cross, London has been designed by Ekho Studio and spans over 21,000 square feet across two floors. The company wanted to use its new King’s Cross HQ to drive collaboration and innovation further with its relocation to London’s new ‘Knowledge Quarter’ bringing them closer to their broad network of healthcare partners to enable them to work in ambitious, purpose-led partnerships.


As part of the stunning design, Ekho Studio used Troldtekt’s acoustic wood wool panelling as part of the specification to combat issues around acoustics and reverberating sound. The design embraced a lot of hard surfaces – from break-out areas and open plan offices stretching around meeting rooms. This, coupled with the full-height windows to maximise natural light all have an impact on acoustic performance.

Troldtekt acoustic panels are available in a variety of different surfaces and colours and combine sound absorption with a tactile surface. With an expected life cycle of at least 50 years and resistance to humidity and impact, they are available in various sizes and four grades, from extreme fine to coarse. The panels can be left untreated or painted in almost any RAL colour. Depending on the panel specified, reaction to fire is classed in accordance with EN 13501 as B-s1,d0 or A2-s1,d0 respectively.

Cradle to Cradle Certified® at Gold level, Troldtekt wood wool acoustic panels are manufactured using wood from certified forests (PEFC and FSC®C115450) and can contribute positively to a building’s BREEAM, WELL or LEED points.
