You could set this in the context of trying to develop sound-absorbing panels in an arena to be used for a gig. A data-logger can be place in a shoe box (the arena). Place a metal tray on the top of the box and drop a small object from a set height to produce a sound. Measure the loudness of the sound. You could then place different numbers of sponges between the box and the tray and measure the loudness of the sound heard in the box.
