Dendrogram Based on the Measured Spectra from Rubber Ball Impact in the 50–200 Hz Range.

Caption

The similarity (as determined by Euclidean distance) of household-specific heavy impact sounds was analyzed using hierarchical cluster analysis. A lower connection point for household lines indicates greater similarity in their impact sounds. Notably, households on the same floor tend to exhibit a higher degree of similarity
