Our specialist in-house installation teams expertly applied SonaSpray fcx in two bespoke whites to feature curved ceilings on both the ground and first floors of the restaurant to create a relaxed and enjoyable atmosphere within the grand dining space.
A deep respect for London’s history and culture lay at the heart of this project, with the restoration aiming to restore and preserve as many surviving original features as possible.
Four Seasons is a brand synonymous with providing the ultimate guest experience, from design and ambience to cuisine and comfort. Aukett Swanke architects and Clarke Saunders Acoustics knew the importance of sound quality for creating a positive guest experience.
However, when working on such a prestige project, aesthetics are always a top priority and any sound solutions would have to work around visual flourishes.
That’s why Oscar Acoustics, an expert in architectural acoustic finishes with an appreciation for great design, was tasked with ensuring multiple public areas of Ten Trinity Square possessed the correct acoustic balance.
Rotunda Lounge
Situated in the heart of the hotel is the Rotunda Lounge, which boasts a beautiful domed ceiling and is wrapped in an impressive plaster relief. This is a splendid space, a sumptuous oasis where guests want to relax. However, it is expansive and capped with a wide central dome, increasing the acoustic challenge. Sound reverberation times needed to be kept to a minimum, and getting the acoustic balance would be vital. As the hotel’s social hub, guests and visitors would need to be able to follow a conversation, yet enjoy the buzz and energy of being in the heart of London.
To solve the problem, ISO 14001 certified Oscar Acoustics used its exceptionally smooth Oscar Elite acoustic plaster, which gives optimal reverberation control. The acoustic finishing plaster was applied onto a mosaic of acoustic Sonaboard and then hand-sanded to give a flawless finish, achieving perfect shapes, not possible with most other systems.
Unlike traditional plaster, Oscar Elite is a synthetic, A2-s1, d0 & Class 0 fire rated acoustic plaster. It absorbs sound energy instead of reflecting it, thereby reducing reverberation times and overall noise. This gives all-important clarity to speech and music, essential within the Rotunda Lounge, which has regular piano recitals. It’s also only 27mm thick in total, making it the thinnest ‘acoustic plaster’ currently available for its performance.
Managing Director at Clarke Saunders Acoustics, Ed Clarke commented on how incredible the live jazz sounded in the space.
“A bit of a first for me; I have never had a musician in tears about how good the acoustics made them sound! We manipulated the acoustics under the reinstated central dome to give musicians just the right balance to support their musical expression, fine-tuning the lounge’s reverberant sound field in the right kind of way. The Oscar Acoustics plaster is a key part of the acoustics finishes design delivering a tonally balanced listening experience.
