25/7 is a sound walk in Kalasatama Park, and is a sci-fi response to Kalasatama’s status as a trial zone for smart city innovations. In the work, Kalasatama residents are fitted with an implant to give them an extra hour per day— but it starts to malfunction for some people.

Snippets of 16 people’s phone conversations are scattered along the paths. Amongst them we hear compositions, which incorporate field recordings made in the Kalasatama area. Using electromagnetic frequency (EMF) microphones, the usually silent signals of electronic devices and infrastructure are fed into into a new audible reality.

How to listen

Download Echoes app to your mobile phone (it’s free!) and use your headphones.

The sound walk starts at the Redi end of Kalasatama Park. The route is marked on the map, and starts at the square Echo.

Tips for the best experience

Download the walk, don’t stream it.

Turn on your phone’s WiFi to improve GPS accuracy. At the start, give the GPS a few seconds to catch up!

When Echoes asks what audio quality you want, choose “professional”.

Off-site listening

Start the walk in the app > click the 3 lines at top right of your screen > turn autoplay off. You can now scroll down and play each Echo.

Access info

Transcripts can be found by tapping on an Echo (a sound bubble on the map), then on “see more”.

All Echoes are on pathways not grass. The last Echo is accessed via steps, but can also be heard on street level at the base of the steps.

The park has a lot of seating. The nearest accessible toilets are in Redi shopping centre, a few minutes away.
