Rion SI-31 SC-95 Octave Band Analyzer

The Rion SI-31 SC-95 Octave Band Analyzer is a dedicated acoustic measurement instrument from Rion that provides real-time octave-band analysis of sound. It delivers spectral information across standard octave bands to help identify dominant frequencies and spectral patterns in noise or vibration signals. Designed for both field surveys and laboratory testing, the SI-31 SC-95 supports acoustical measurements used in workplace noise assessments, environmental noise studies, and machinery or product testing where understanding frequency content informs mitigation and design decisions. By integrating with Rion’s broader measuring ecosystem, it offers a straightforward workflow for collecting, reviewing, and communicating octave-band results to support engineering analysis and documentation.
