Acoustically Noticeable Paths

Although illumination provides security, as one can see who or what is in front, lighting also has a blind spot: everything that lies behind oneself.

Paths must be made of sand, wood chips, gravel or soil, as steps on these surfaces can then be perceived acoustically. Therefore, one can be sure that if only the own steps are noticeable, no one is walking behind oneself.

In addition, these paths also contribute to sustainability, as they do not seal surfaces. This reduces the process of heating up of a city by avoiding sunlight-absorbing asphalt. Furthermore, rainfall can be absorbed naturally and discharged into the groundwater.
