25/7

In collaboration with composer Juuli Haverinen

A sound walk in Kalasatama Park, 25/7 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 phone calls are scattered along the paths. Among them we hear compositions, which incorporate field recordings made in the Kalasatama area. Using electromagnetic frequency (EMF) mics, 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.

Echoes iPhone link Echoes Android link

Open the app and search for 25/7 (EN version)

The sound walk starts here, at Redi end of the park:

In the app, start at the square Echo (a sound bubble):

Tips for the best experience

Download the walk, don’t stream it.

Choose “professional” when Echoes asks which audio quality you’d like.

Check that your phone’s WiFi is on, to improve GPS accuracy. You don’t need to connect to any network!

At the start of the walk, give the GPS a few seconds to catch up.

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. Watch out for road traffic!

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