Absorption and Reflection

Walking and cycling tunnel

The reflections of the tunnel creates a strong boost and a clear, almost musical tone when the bikes passes. The sound response provides an interaction with the architecture;  you can often hear children and others try the acoustics with different exclamations. How does concrete sound?

Absorption and reflection

Documentation of a central square area with and without snow. The traffic intensity was similar on both occasions.

Snow absorbs sounds, and so does for example soil and peat. A greener city will therefore involve a lower background noise and create better conditions for a more relevant audio environment, where completely new sounds will be able to come out.

Water wall

Water falls directly against hard material which creates a relatively high-frequency sound. The sound is reflected and reinforced against the wall, and once again toned  by the material.
