Flis Holland, with composer Juuli Haverinen.
NOTE! The start is NOT at the metal gate where the QR-code sign is fixed. It is 50 metres to the right!
In the app, start at the square Echo (a sound bubble on the map). It is at the Redi end of the park.
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.
About the sound walk
25/7 is a sound walk in Kalasatama Park, Helsinki. This sci-fi work responds 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.
A series of 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.

Welcome to Kalasatama district, our city’s Living Lab. Here, smart devices and services are designed…

Or start creating tours, treasure hunts, POI maps... Just let your imagination guide you.
