The Room Acoustics Reporter is a PC software for automatically generating reverberation time measurement reports and analyzing the frequency response spectrum. The software supports acousticians and experts in the visualization and detailed evaluation of measurement data recorded with the Sound Level Meter.
Reverberation Time according to ISO 3382, DIN 18041, etc.
Room acoustic prediction (Sabine, Eyring)
Import of user-defined absorber data and tolerances
Analysis of 1/1 and 1/3 spectra as well as Noise Curves
Standard-compliant reporting
Analyzing Reverberation Time or Noise Spectra
The Room Acoustics Reporter software is the ideal tool for data analysis and reporting of the following measurements:
Reverberation Time
Before / after comparison of acoustic room treatments
Adding sound-absorbing materials for evaluation
Comparison with standard-specific tolerances
Frequency Response Spectrum (RTA)
Averaging of noise spectra recorded at multiple measurement positions
Calculation of the sound level difference D between two rooms
Background noise correction
Noise Curves, 1/12 Octave and XL2 Cinema Meter
Verification of measurement results using tolerance data for a pass/fail decision
Automatic conversion of 1/12 octave data into one-third-octave bands
Creation of standard-compliant measurement reports
Drag & drop the measurement data into the software. All measurement data is automatically assigned to the corresponding data set before or after changing the acoustic properties of the room.
Calculations View
Evaluate the individual data sets for each measurement. The software presents the reverberation time spectrum of the room.
Results View
The Room Acoustics Reporter displays the average reverberation time in a table and in a standard 50 Hz to 10 kHz graph. At the same time, the average reverberation time in the middle frequency range (Tmid) is calculated.
The Room Acoustics Reporter software can simulate the influence of additional acoustic absorbers installed in the room. Customer-specific absorption coefficients of surface absorbers or objects can be imported into the software. The software calculates the expected new reverberation time and the resulting sound level change in the room. In addition, it presents the A/V ratio and the average sound absorption coefficient in the room. The simulation is performed according to Sabine’s formula and the DIN EN 12354-6 standard. For rooms with higher absorption, the simulation can also be performed according to Eyring.

Reporting
With the completed descriptions of the measurements taken, the standardized measurement report is ready for printing. Customized documentation is supported by the user-defined logo and signature.
Frequency Response Spectrum
The Room Acoustics Reporter calculates the average of the imported octave or one-third-octave spectra and compares the result against the specified tolerance range. In addition, you can display the level sum or difference of two data sets in the measurement report. The software supports data recorded by the measurement function Spectrum (RTA) as well as the specific XL2 functions Noise Curves, 1/12 Octave and Cinema Meter.
Noise Curves
Room Acoustics Reporter offers a dedicated solution for generating standardized noise curve reports. The software calculates the average background noise spectrum in the room. This may be compared with the target range – based on the usage of the room. The software supports data recorded by the measurement function Spectrum (RTA) as well as the specific XL2 functions Noise Curves, 1/12 Octave and Cinema Meter.
Room Acoustics Reporter supports the following Noise Curve standards:
Noise Criteria NC (ANSI/ASA S12.2-2019)
Room Noise Criterion RNC (ANSI/ASA S12.2-2019)
Noise Rating NR (ISO/R 1996-1971)
Grenzkurven GK (DIN 15996:2020)
Sound Absorption Coefficient
The ISO 354 and ASTM C423 standards specify a method for determining the sound absorption coefficient of acoustic materials used to clad walls and ceilings, or the equivalent sound absorption area of individual objects such as furniture or people in the room.
The reverberation time is measured with the Sound Level Meter, with and without absorbers in the room. Based on this data, the Room Acoustics Reporter software calculates the sound absorption coefficient according to the ISO 354, ISO 11654 and ASTM C423 standards. The standardized measurement report also gives the sound absorber class A-E and the single-number values NRC (Noise Reduction Coefficient) and SAA (Sound Absorption Average).

Trusted by professionals worldwide.
As a research laboratory invested in supporting communities through real time noise monitoring, I am very happy to exclusively use NTi instruments. Not only are the robust, easy to use, and provide high quality data, the customer service is outstanding and their team will work with you to find the most cost effective and appropriate solutions needed for problems ranging from easy to difficult.
Erica D. Walker MSc, ScD, RGSS Assistant Professor of Epidemiology, Brown University School of Public Health
I’ve been using the XL2 for over 15 years for short-term and long-term measurements in all kinds of indoor and outdoor environments all across the country. The meter gets me what I want, when I need it. It’s not only the best value for acoustical measurements, it’s the best tool period. I bet my company and reputation on XL2 results and it has not let me down. You would be crazy not to consider adding NTi instruments to your toolkit.

We at Constructure GmbH use two XL3 sound level meters for noise monitoring during demolition work. We are very satisfied with these highly user-friendly instruments, the online monitoring in the MeasurEye Cloud, the good advice and qualified support. Factory calibrations at NTi Audio are also handled very smoothly and without complications.
