Nor286 ORIGAMI Impulse Sound Source

Innovative foldable impulse sound source for room acoustics.

Overview

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 repea…

Frequently Asked Questions

  • When should I use ORIGAMI instead of a loudspeaker?
    ORIGAMI is ideal for quick surveys, preliminary assessments, and situations where electronic sound sources are impractical or time-consuming to set up. For detailed measurements requiring precise spectral control, a dodecahedron loudspeaker system provides more controlled excitation.
  • Is the impulse repeatable?
    Yes, the ORIGAMI's patented mechanical design provides consistent impulse characteristics across repeated measurements, ensuring reliable reverberation time and room acoustic parameter calculations.
  • Does the ORIGAMI meet ISO 3382 requirements?
    The ORIGAMI generates impulses suitable for ISO 3382 room acoustic parameter measurements including reverberation time (T20, T30, EDT). It provides adequate energy and bandwidth for most room sizes encountered in practice.

Application Guide

The Nor286 ORIGAMI Impulse Sound Source belongs to the Norsonic Sound Source range. See the Sound Source application guide for system configuration, compatible accessories, and applicable measurement standards.
