IMIAD | Hemp and Acoustics

Hemp and Acoustics | 3rd semester | Winter semester 2023/24

The third semester students spent a semester experimenting with hemp as a natural building material. The result is acoustic elements made from hemp shives, which are obtained from the wooden core of the plant stem. In combination with natural lime or geopolymer, the building material combines a variety of different properties. One of these is its excellent acoustic effectiveness.

As part of the project, the sound absorption of the individual elements was tested at the Center for Building Physics at the HFT Stuttgart site in Vaihingen. This gave the students an in-depth insight into acoustic measurement methods and working in the building physics laboratory.

At the end of the semester project, an exhibition was opened, sponsored by the association “Freunde der Hochschule für Technik Stuttgart e.V.”.

We would like to thank Wöllner GmbH, Xatico, Felde Fibres GmbH, von Hanf GmbH and hemp engineer Henrik Pauly for their support of the project.
