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 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.
