Mobile demonstration device for sound-reducing tiles

A method of using a sound-reducing tile demonstration device, the method comprising:

• placing a first sound-reducing tile in a first portion of an assembly, the first sound-reducing tile having a first sound transmission property;
• activating a sound emitting device disposed within an interior volume defined by the assembly such that sound exiting the interior volume passes through the first sound-reducing tile;
• measuring a first sound level at a first position exterior to the assembly;
• placing a second sound-reducing tile in the first portion of the assembly, the second sound-reducing tile having a second sound transmission property that is different than the first sound transmission property;
• activating the sound emitting device disposed within the interior volume defined by the assembly such that sound exiting the interior volume passes through the second sound-reducing tile;
• and
• measuring a second sound level at the first position exterior to the assembly.

An assembly for demonstrating sound transmission properties, the assembly comprising:

• a base portion including at least one side wall, the base portion extending from a first end to a second end along an assembly axis, the at least one side wall at least partially defining an interior volume, wherein the at least one side wall defines a base perimeter when viewed along the assembly axis;
• a tray portion having a bottom wall and at least one tray side wall that upwardly extends from the bottom wall, the at least one tray side wall extending from a first end to a second end along the assembly axis, wherein the bottom wall is disposed at or adjacent to the first end of the at least one tray side wall, wherein the at least one tray side wall defines a tray perimeter when viewed along the assembly axis,
• the tray perimeter corresponding in shape to the base perimeter such that an outer surface of the at least one tray side wall is adjacent to the inner surface of the at least one side wall of the base portion, an inner surface of the at least one tray side wall and a top surface of the bottom wall cooperate to define a tray volume, wherein a cutout portion extends through a portion of the bottom wall of the tray portion to form a transmission aperture;
• and
• a first sound-reducing tile disposed at least partially within the tray volume such that a portion of the first sound-reducing tile completely covers the transmission aperture, the first sound-reducing tile having a first sound transmission property.
