Nor286 ORIGAMI Impulse Sound Source

The Nor286 ORIGAMI is an innovative, foldable impulse sound source designed for quick and reliable room acoustics measurements. This patented mechanical device generates a high-energy, broadband acoustic impulse without requiring any electronic components, batteries, or amplification equipment. Simply unfold the ORIGAMI, position it in the room, and trigger the impulse mechanism to produce a repeatable excitation suitable for reverberation time and room acoustic parameter measurements per ISO 3382. The ORIGAMI fills a critical gap between traditional impulse sources such as starter pistols and balloon pops, which offer limited repeatability and frequency coverage, and full dodecahedron loudspeaker systems that require amplifiers, cables, and significant setup time. The Nor286 provides consistent impulse characteristics with sufficient energy across the frequency range needed for accurate T20, T30, and EDT calculations, while its foldable design collapses to a compact package for effortless transport between measurement locations. For building acoustics consultants and facility managers conducting quick room acoustics surveys, the ORIGAMI dramatically reduces measurement time compared to setting up a complete loudspeaker source chain. It is particularly valuable for preliminary assessments of concert halls, classrooms, auditoriums, worship spaces, and office environments across the GCC where reverberation characteristics directly impact speech intelligibility and occupant comfort. The Nor286 is also an excellent educational tool for acoustics training programs at universities and professional development courses.
