IMPACT SOUNDS

A set of impact sounds that were produced using four rods with the same length and diameter but made of different materials. A wooden rod, with a much shorter length but the same diameter, was used as a mallet. Several impacts were recorded for each rod, and the location of the impacts as well as the impact force varied slightly from one instance to the other. The sounds were digitized using a sampling frequency of 44100 Hz.

The sounds included here are impacts on the edge or center of the rods. These are in Matlab files with one matrix with a sound in each column. For more sounds of this type (but from rods with other lengths, etc.) please contact Sofia.
