Abstract
An assembly for demonstrating sound transmission properties includes a base portion and a tray portion partially defining a transmission aperture is removably inserted into a portion of the base portion. A first sound-reducing tile having a first sound transmission property is placed in the tray portion and a sound generating device disposed in an interior volume of the base portion emits sound that is attenuated by the first sound-reducing tile as the sound exits the transmission aperture. A second sound-reducing tile having a second sound transmission property is placed in the tray portion and the sound generating device disposed in the interior volume of the base portion emits sound that is attenuated by the second sound-reducing tile as the sound exits the transmission aperture. A sound measuring device disposed outside the interior volume device can compare the first and second sound transmission properties.
