NTi Audio Announces Sound Insulation PC Software and Updated Sound Level Measurement Report for XL2

March 10 2017, 06:00
NTi Audio launched a new professional software package for determining the sound insulation of buildings measured with its XL2 Sound Level Meter. The “Sound Insulation Reporter” PC software generates simple yet detailed sound measurement reports that comply with existing standards, ideal for acoustic consultants. The newly-designed SLM Reporting Tool presents the results of measurements recorded with the XL2 in a flexible measurement report.

The new "Sound Insulation Reporter" software ideally complements the XL2 Sound Level Meter. The measuring instrument and software together make an intuitive solution for the detailed analysis and documentation of sound insulation measurement data. “The Sound Insulation Reporter produces measurement reports for airborne and impact sound insulation in accordance with the relevant standards such as ISO140 and, of course, the new ISO16283,” project manager Berno Nigsch explains.

The measured data recorded in the source and receiving rooms can be simply dragged and dropped into the "Sound Insulation Reporter". The results are then automatically calculated and immediately shown without any further action required from the user. The standard-compliant measurement reports are ready to print and include sound insulation charts and all associated data – as well as a company logo of the user’s choice. The insulation level is documented within the frequency range 50 Hz to 5 kHz. Furthermore, the user can add descriptions of the measured partition or ceiling directly into the measurement report.

The "Sound Insulation Reporter" and the XL2 work hand in hand; at the first time the user chooses names for the various measurement positions on the PC. These names are then stored on the XL2 memory card and the files of each measurement series are clearly labelled for later reference. When importing the measurement files, the PC software recognizes which of the files belongs to which measurement position. Thus, the user benefits from an enormous increase in efficiency – it is only a matter of seconds between the import of the prepared measurement data and the availability of the finished report.

The "Sound Insulation Reporter" calculates the energy-average of the third-octave spectra and performs any necessary noise correction for the receiving room data according to the selected standard. Analogously, the reporter calculates the average reverberation time from the individual measurements in the receiving room. The software automatically updates the averaged and sound insulation values when individual measurements are removed from the evaluation or other parameters are changed. All measurement data and charts are available via copy & paste for customer-specific reports.

The "Sound Insulation Reporter" software can be installed on any number of computers. This facilitates, for example, evaluation with a notebook on site and later with the office PC. The import of data into the PC software is enabled by the Sound Insulation Option being installed on the XL2 Sound Level Meter. As an alternative to purchasing this option, the annual subscription service "Sound Insulation Reporter 365" offers an inexpensive way for the data import into the PC software. The instrument supports the Sound Insulation Option from firmware V3.23 and higher.

Newly-designed Sound Level Measurement Report
The SLM Reporting Tool is a newly-built measurement report based on Microsoft Excel for Windows. It displays the broadband level recorded with the XL2 Sound Level Meter for analysis and documentation of the measurement results.

The XL2 Sound Level Meter stores all measured values on its SD card in text format (txt file) for documentation and further analysis. These files can be opened with a text editor or imported directly into MS Excel. Based on these txt-files, the recorded broadband sound levels can now be loaded directly into the SLM Reporting Tool at the push of a button. After entering the measuring location and descriptions, the measurement report is ready for printing.

The customer-specific input windows are flexible. The user can select between a measurement report for live event monitoring or a general ambient noise measurement. In addition, the title of each window can be adapted individually to the needs of the customer. "The SLM Reporting Tool is the result of many customer requests for a flexible measurement report. Customers can now access this form and clearly document their sound level measurements with a few mouse clicks,” says Berno Nigsch. “Country-specific measurement reports, such as for the event monitoring according to Vlaamse Geluidsnormen in Belgium or DIN15905 in Germany, are selectable by mouse click. Any applicable limit values are automatically displayed.

The SLM Reporting Tool is offered free of charge for all registered XL2 customers. It replaces all previous measurement report forms and supports Microsoft Excel 2016, 2013 and 2010 for PC. For a more comprehensive analysis of logged sound level data, the optional XL2 Data Explorer software is available. It also displays the third band spectrum and playing the audio data synchronously with the level.
