The document describes an experiment to determine which common insulating material - wood, bubble wrap, Styrofoam, newspaper, or cardboard - is most effective at insulating sound, as measured in decibels. The hypothesis was that Styrofoam would insulate sound the most, but the results found that a wood box provided the best insulation against sound. The document lists materials needed for the experiment and references on sound insulation and measurement.

cardboard, will insulate an alarm sound the most, measured in decibels?
