Ottolenghi have always taken soundproofing within their restaurants very seriously to ensure that their diners have the best experience possible. To date they currently have a SonaSpray acoustic spray ceiling in Ottolenghi Spitalfields, an Oscar Elite acoustic plaster ceiling in Nopi, Warwick Street, and most recently an Oscar Elite acoustic plaster ceiling in the beautiful new restaurant Rovi in Fitzrovia, London.
Oscar Elite smooth synthetic acoustic plaster finish with the appearance of conventional painted plaster
Unlike traditional plaster, this synthetic acoustic plaster absorbs sound energy instead of reflecting it, thereby reducing reverberation times and overall noise levels, giving all important clarity to speech and music.
A beautiful room with simple surfaces such as feature wood floors and plain flat walls will be visually appealing but may not be the most pleasurable place to spend time due to poor acoustics.
The same visual impact combined with a sympathetic and relaxing acoustic ambience is possible with Oscar Elite synthetic acoustic plaster spray applied to create an acoustic ceiling and control noise reverberation.
Architects and interior designers who incorporate Oscar Elite acoustic plaster into their designs can achieve spatial design with hard smooth surfaces without compromising the acoustic ambience.
This was the case with the Holland Park Grand Designs house in London. During refurbishment, Oscar Elite acoustic plaster was applied to the ceiling and inside of the lightwell, resulting in superb acoustics without compromising the beautiful, flat and smooth surfaces.
- Oscar Elite acoustic plaster can be directly applied to most substrates such as wood, gypsum board, concrete etc.
- Oscar Elite acoustic spray plaster installations are applied at 27mm thick; the area is dependent on the acoustical requirements of the project. An air gap is introduced to achieve high absorption at low frequencies.
- Oscar Elite acoustic plaster is fire rated BS476: Class 1 to Part 7 and Class 0 to part 6.
What people say about our SonaSpray Elite installations...
"Yotam Ottolenghi used Oscar Acoustics to render shiny surfaces softly spoken."
Oscar Acoustics are very proud to have been mentioned in the Evening Standard, for the superb acoustic result achieved in the beautiful restaurant NOPI by using our exceptionally smooth Oscar Elite acoustic plaster.
“It’s time to talk about noise in restaurants…I don’t always – just sometimes – harp on about the unpleasantness of sound ricocheting off unforgiving surfaces, thumping music shivering your timbers and having to give up on the idea of conversation with dinner. Hiring an acoustic engineer when a new restaurant is planned is an expensive move but two of the most successful operators I know make it top of their list of priorities.”
“Saved us money.
Saved us time.
Very proactive and great at problem solving.
Gave us some good ideas, issued samples and went out of their way for us...”
Operations Director, Overbury PLC
“We are very pleased with the finished product and would like to thank you, your management team and Mark and John (installers) for enabling us to meet our objective."

Oscar Elite Installations
When designing this beautiful industrial chic office reception area in the heart of London, the architects required the very smoothest of acoustic finishes to realise the minimal design intent with superb office acoustics. Oscar Elite acoustic plaster was expertly applied onto an MF plasterboard ceiling by Oscar Acoustics' in-house installation team to enable the incorporation of access hatches, ventillation grills and recess lighting.
Our Oscar Elite smooth acoustic plaster was spray applied to the ceiling in the stylish Holborn Dining room at the Rosewood Hotel, London. This synthetic acoustic plaster absorbs sound energy instead of reflecting it, reducing reverberation times and overall noise levels for perfect restaurant acoustics.
For this exquisite dining room, the restaurant and bar acoustics had to be dealt with using cutting edge acoustic plaster technology so as to not compromise any of the design brief. Martin Brudnizki Design Studio wanted to redesign Fortnum & Mason’s original Fountain Restaurant with a design that fused the glamour of contemporary London with the heritage of the truly iconic department store.
When designing Nopi, the owner Noam Bar had a clear vision: plaster smooth ceilings, painted brick and tiled walls, hard table tops and marble floors; poor restaurant acoustics were a certainty.

New College is one of the largest Oxford colleges, with some 400 undergraduates and nearly 200 graduates. It is, as all Oxford colleges, an autonomous, self-governing institution.
The new building has been described as an architectural gem. Designed by the creators of the London Eye, Marks Barfield Architects and featuring stunning materials and spaces, The Lightbox is intended to appeal to young and old alike.
Oscar Elite Technical Specification
NBS Product Specification
Oscar Elite installation structure
The 27mm construction consists of 2mm adhesive, 20mm thick mineral board, base and top coat Oscar Elite synthetic acoustic plaster totalling approximately 5mm, which is sprayed, trowelled and worked to optical requirements.
The finish is visually hard and firm to the touch but with excellent sound absorption. As with all acoustic plaster, installations should be suitably protected in areas where damage is likely.
Oscar Elite acoustic plaster is installed by our own in house, trained staff in order to guarantee optimal workmanship.

Maintenance & cleaning
Dust is removed by lightly brushing or vacuuming with a soft brush head. It is also sometimes possible to blow dirt from the surface with a high pressure air hose. A wall or a ceiling can be entirely over sprayed in acoustic plaster in the same or a change of colour. Over painting must be done by spraying and not roller to prevent serious impact on the acoustic performance and damage to the product. Advice must be sought from Oscar Acoustics before painting as incorrect application can result in damage of the product.
Repairing & servicing
A major benefit of our new Oscar Elite is its ability in most cases, to be locally and invisibly repaired, negating the need for expensive and inconvenient pre-handover resprays, as with many products similar in appearance. For more serious damage, it is possible for us to lightly sand and reapply the top coat.
Recessed services e.g. spot lighting will require a halo spacer to match the material depth. Oscar Acoustics manufacture and install stainless steel halo spacers (drawing available) to the same size as the hole cut out. Stop beads may be required around openings which again we can supply and install. Specially designed access hatches are also available through Profab, enabling the Oscar Elite to continue across the hatch door. Problems can arrise from using other hatches. These items are at extra cost and are to be purchased direct from the Profab. Please contact Oscar Acoustics for details and item code. Surface mounted fittings e.g. hanging/pendant lights will require pattresses to match the material depth. Please contact Oscar Acoustics for further advice.
Please Note: 90% of flangeless fittings do not work properly with any acoustic finish. If you are specifying a flangless fitting, please contact Oscar Acoustics for advice.
Our technical department offer free advice and acoustic calculations on the use of our products.
