Sound absorption of granular materials — •Tamara Zühlsdorff¹, Anna-Maria Daxlberger¹, and Thomas Grillenbeck^1,2 — ¹Ignaz-Günther-Gymnasium Rosenheim — ²Fakultät für angewandte Natur- und Geisteswissenschaften, Fachhochschule Rosenheim

We examine the sound absorption coefficent of granules. We are especially interested in how the sound absorption depends on the state and the history of the material. Our experiment is implimented with variant of "Kundt's pipe" which sents an acoustic noise to granules and appraises the results. With these data we can calculate the sound absorption coefficient.
