Gone are the days of measuring reverberation time with a starter pistol or spending endless hours inflating balloons with your lungs.

Developed by the Kobayasi Institute of Physical Research in Japan, the Nor286 Origami Impulse Source offers a simple, convenient, and lightweight solution for reverberation time measurements. Made from paper,  the origami impulse source requires nothing more than a quick snap of the tool to generate an impulse source.

Users can expect up to 100 uses from a single Origami Impulse Source.
