Acoustic coatings case study

The home of time itself,  the Royal Observatory is one of the most important historic scientific sites in the world.  Founded by Charles II in 1675 it is known throughout the world as being the official starting point for each new day, year and millennium.

The Royal Observatory underwent a major £15 million redevelopment which included new galleries, an education centre and a state-of-the-art planetarium. 

During the fit out of the planetarium prior to the application of our SonaSpray acoustic decorative finish, it was noticed by all how reverberant the dome was.  Finding an acoustic product that would take the shape of the dome, appear as black as night and invisible to the audience, would normally have been an ordeal but the reverberation problem was solved using our through coloured, black SonaSpray K-13 noise reduction coating from our extensive range of acoustic decorative finishes.

The Royal Observatory, London - SonaSpray K-13


Acoustic Coatings

Arup Acoustics, the acoustic installation project consultants, carried out an extensive acoustic analysis of the new planetarium before construction.  SonaSpray K-13 was then specified at 50mm thick for the curved concrete walls and 75mm thick for the discoid ceiling.  The acoustic coating was installed in 4 days, spraying to the required thickness in one coat.  With our SonaSpray K-13 acoustic spray applied within this facility the acoustic ambience is fundamental to the success of the venue.

Other planetariums with similar reverberation issues that have used SonaSpray acoustic coating to excellent effect are the National Space Centre Planetarium, Leicester & Bristol Planetarium.

Results: Superb building acoustics by using our extensive range of acoustic coatings.
