The research focuses on two temporary pavilions designed as acoustic shelters in an urban open space: the Serpentine Gallery Pavilion built in the forecourt of the Serpentine Gallery in Kensington Gardens in 2011 and the Be Open Sound Portal pavilion built at Trafalgar Square in 2012, both heritage sites in London. Swiss architect Peter Zumthor designed the former pavilion, while the latter was designed by the English firm Arup. It was recognized that the same soundscape design model - an acoustic shelter - was applied in open spaces of a different aural context. Both were dismantled before the time of this research. With an aim to show the types of soundscape from which acoustic shelters in an urban open space could shield, monaural onsite measurements were performed in October 2015 to analyze aural context differences between the immediate surroundings of the two former pavilions. The difference is clearly visible in the frequency of sonic events, their spectral composition and average sound pressure levels.
