Room Acoustics Reporter

Room Acoustic Software

The Room Acoustics Reporter is a PC software for automatically generating reverberation time measurement reports and analyzing the RTA frequency response spectrum. The software supports acousticians and experts in the visualization and detailed evaluation of measurement data recorded with the XL2 Sound Level Meter.

At a glance

  • Reverberation time RT60 according to the ISO 3382 or DIN 18041 standards
  • Import of absorption coefficients
  • Comparison before / after acoustic measurements
  • RTA frequency response spectrum according to the IEC 60260 standard
  • 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 RT60
    • Before / after comparison of acoustic measurements
    • Adding sound-absorbing materials for evaluation
    • Comparison with standard-specific tolerances
  • RTA frequency response spectrum
    • Averaging of noise spectra recorded at multiple measurement positionsa
    • Calculation of the sound level difference D between two rooms
    • Background noise correction

Measurements View

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.

How to import my data sets into the Room Acoustics Reporter?

Room Acoustics Reporter 365

The purchase of a Room Acoustics Reporter 365 subscription allows the unlimited import of measurement data from one XL2 Sound Level Meter into the Room Acoustics Reporter PC-Software for a period of one year. Data which has been recorded prior the installation of the Room Acoustics Option may then also be imported.

Room Acoustics Option

A permanent license is available as an alternative to the annual subscription service. The Room Acoustics Option installed on a XL2 enables the unlimited import of measurement data into the Room Acoustics Reporter PC-Software.

Installation on multiple PCs

The Room Acoustics Reporter software can be installed on multiple computers. This provides experts with the freedom to distribute their measurement projects among team members and clients.

Using the software with full functionalities

The full software functionality is enabled by having the following options installed in the XL2 Sound Level Meter:

  • Extended Acoustic Pack (activates the functionality for measuring the reverberation time RT60 in the third-octave band)
  • Room Acoustics Reporter 365 or Room Acoustics Option
