Wood, Water, Metal, Earth, and Radio Waves – Leiden (Un)Heard

room 14 ECHOES


This series of four Leiden soundwalks invites you to listen to Leiden through other “ears,” using recording techniques to give us new perspectives on known places or to listen in on spaces that usually go unheard. In this walk we make use of hydrophones, contact mics, geophone and a VLF (very low frequency) antennae to listen to vibrational worlds in the water, within matter, underground, and the very low frequencies continually propagated through the air, yet outside our range of hearing, such as radio or perhaps even atmospheric noise.

What frequencies can both humans and mice hear in Central Station? How does a bridge sound through contact mics? What does the outside world sound like within a WWII bunker or from a sensitive microphone tuned into the vibrations of the earth? How does turning the pages of a 400 year old book or a weaver working on a 200 year old loom sound? Hopefully these (Un)Heard sounds will give your ears a listen into the sonic possibilities of this cities and what can be discovered through listening everywhere you go!"
