The Unheard: A Listening Salon about Ultrasound and Twilight

Enlarge

As the world grows quiet at the end of day, the world of bats awakens. On an evening walk, we will explore the acoustic landscapes of dusk. An invitation to technologically mediated listening and to immersing oneself in echolocation, ultrasound, and the hidden sounds of the evening.
Listening Salons are an art/science format from CitySoundscapes. Participation by registration.

Start:8:30 pm, duration approx. 1 hour, followed by an informal wrap‑up

Registration here. You also need a valid ticket for the "Lange Nacht der Musik" event.
