Building Sound Insulation Measurement System
Model: SC420
Solutions for building sound insulation and reverberation time
Comply with ISO 16283-1 and ISO 140 to measure, calculate and generate sound insulation reports.
For on-site and indoor sound insulation measurement laboratories. CESVA provides a complete and simple solution.
GIP covers all processes: shipping + assembly + calibration + measurement + calculation + reporting. A range of accessories has also been developed to fully meet the requirements specified in airborne sound, external wall and floor impact sound insulation measurements.

Obtaining decay curves from impulse responses:Schroeder's method of backward integration. Decay curve slope estimation:Automatic estimation of decay curves based on least squares fit , linear regression analysis. Quality indicators: nonlinear parameters, curvature C and B·T product bands . Random Incidence Filter: It has a selectable random incidence filter.
