Room Acoustics Reporter

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.

Evaluate the individual data sets for each measurement. The software presents the reverberation time spectrum of the room.

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 RT60mid 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.

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.

The Room Acoustics Reporter calculates the average of the imported 1/3 octave spectra and compares the result against a tolerance range. In addition, you can display the level sum or difference of two data sets in the measurement report. The measurement data of the following XL2 functions can be imported: RTA, Noise Curves, 1/12 Octave and Cinema Meter.

Noise Curves are used to evaluate background noise in rooms. Load the frequency spectrum, measured with the XL2, into the software, and the measurement report presents a clear comparison of the measurement data within the target range.

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 XL2 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).

Feel free to test the Room Acoustics Reporter software with demo data. Room Acoustics Reporter is a free-to-use PC software. The data import from the XL2 Sound Level Meter is chargeable.

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 1/3 octave band)
• Room Acoustics Reporter 365 or Room Acoustics Option
