Echoes of our time
A project by Oscar Björk
Echoes of our Time began with funding from the Swedish Arts Grants Committee (Kulturbryggan) between 2020–2022. The project set out to create Sweden’s first libraries of acoustics — a collection of Acoustical measurements (IR files) captured in culturally significant and unique locations across the country. These files were donated to a Swedens national archive to ensure their long-term preservation for future generations.
The second goal of the project was to explore these places through their acoustic identities. This resulted in interactive exhibitions at two museums, focusing on acoustics and cultural heritage, where visitors could experience and manipulate the acoustics of each location in real time through modern technology.

Acoustics from our surroundings is something we experience daily but rarely gets much focus. It is often in places where we meet powerful reverberation, for example in a church, that it becomes clear that the acoustics are a large part of the overall experience itself. People save photographs, videos and audio recordings to document their lives and experiences. The acoustics of places are not commonly preserved in a way that allows people from different parts of the world to experience the place by interacting or using its acoustics.
The collected IR-files captured during the project Echoes of our time was donated to Swedens national archive (Riksarkivet) in October 2022. The first exhibition took place at the Sigtuna Museum between May and November 2022. The second exhibition took place at Sundsvalls Museum February to May 2024.

Stockholm City Hall - Golden Hall
Stockholm City Hall was inaugurated on 23 June 1923 and is the seat of Stockholm Municipality, Sweden. It stands on the eastern tip of Kungsholmen island, next to Riddarfjärden's northern shore and facing the islands of Riddarholmen and Södermalm. It houses offices and conference rooms as well as ceremonial halls. It is the venue of the Nobel Prize banquet and is one of Stockholm's major tourist attractions.
The Golden Hall is a banqueting hall Measuring 44-metre (144 ft) in length, it received its name when its walls were decorated by mosaics created by the artist Einar Forseth on a proposal by the City Hall architect Ragnar Östberg.

The Work
PROJECT LEADER - OSCAR BJÖRK:
The idea started with a walk in the nearby castle park with my daughter.
I think I have been inspired by the environment I live in. I live in the alley next to Venngarn's castle, and here in the vicinity there are large mighty natural areas, well-kept buildings and much is
preserved and inspired from the 1600s and 1700s.
As a sound engineer, my job is to capture and preserve audio in a digital format. And to preserve a building or environment in audio format feels very unusual when compared to something visual like a photograph.
I am a guitarist, and i have learned the technique of impulse responses as it has become very common to use for sampling of different guitar/bass cabinets. The files is used in the computer or a digital sampler instead of bringing an actual guitar/bass cabinet to the studio or live show.
With the same method, it is possible to capture the resonance of a room, so-called
"convolution reverb". But it is a slightly different approach because you are not primarily looking to
capture the character of speakers or microphones, but instead the surrounding environment.
It is easy to argue that an impulse response file could be as valuable as a photograph. And it
really feels quite reasonable to preserve a place in an audio format as well as figuratively.
The technology with impulse responses has been used for more than 20 years, but I am sertant that it has not yet reached its full potential.
