NDI Audio has released an updated version of its Room Acoustics Reporter PC software, adding support for the evaluation of noise curves using NC-2008, RNC-2008 and NR methods, allowing for measured third-octave spectra to be compared with the limit curves according to the DIN 15996 standard.
The software uses reverberation time data measured by the XL2 acoustic analyser, allowing measurement reports to be created according to ISO, ANSI and other standards.
A built-in library of absorption coefficients of insulation material is included, allowing users to apply these materials to a simulation to demonstrate changes.
Measurement (in a reverberation room) of the absorption coefficient of a material is also available according to ASTM C423-17 and ISO 354:2003 standards.
