A scalable sound insulation measurement system that grows with you

A scalable sound insulation measurement system that grows with you

Measuring airborne, façade, and impact sound insulation follows a standardized procedure involving several measurement steps. Depending on which sound insulation test you are performing, you will need a sound level meter, a loudspeaker, and a tapping machine. To better meet our customers' needs, NTi Audio has developed the EXEL Building Acoustic Kit, a collection of measurement tools optimized for low weight, simple operation, and excellent performance. All at an attractive price.

The XL2 Sound Level Meter takes the measurements

The XL2 Sound Level Meter quickly and easily takes 1/3rd-octave level and reverberation time measurements required for the rating of insulation against airborne, impact, and façade sound transmission. All measurements are executed in accordance with ISO 16283, ISO 140 and the Approved Document E in England and Wales. For fast integration into existing software tools, the XL2 saves data directly as text files. No need to install proprietary software utilities to access your data.

XL2 Sound Insulation Reporter for organizations that want to be noise consultants and not software developers

The standards specify the calculations needed for measuring airborne, impact, and façade sound transmission. If you are one of those noise consulting experts that do not wish to invest time to initially develop the reporting tools and then maintain them as the standards and software like Microsoft Excel change, NTi Audio has just the right reporting tool for you. The XL2 Sound Insulation Reporter for Windows PCs. It is available with either a permanent license, always-free upgrades, or with a one-year rental which can be charged to specific customer jobs.

Test faster and quieter with remote control of sound level meter(s) and speaker

The XL2 Sound Level Meter and the new DS3 Dodecahedron Speaker can be controlled remotely. The DS3 Dodecahedron Speaker is usefully loud. To reduce noise pollution and the time required to wear hearing protection, the DS3 can be remotely turned on/off with a wireless handheld mini remote control. Alternatively, a PC running the XL2 Sound Insulation Reporter can remotely (over Wi-Fi) turn the DS3 omnidirectional speaker on automatically during measurement and then off at the end. All from outside the source room. A second XL2 reduces the time to test a partition. Source and receiving room measurements can be taken simultaneously. XL2 Sound Insulation Reporter even compensates for the individual frequency response of each measurement microphone.

Verify results in the field before heading home

Many consultants have had the experience, or live with the fear, of taking the measurements, packing up the system, returning to the office and, while preparing the report, wishing they were still on site to do one more test. Remote control of the XL2 Sound Level Meter with the Sound Insulation Reporter PC software means the results are shown immediately on the computer screen. Use the same software in the field that you use back in the office to finish the calculations and see the final results; not a cramped interface compromised to work on a handheld’s limited screen with data from only one sound level meter. Decide if the compromises inherent in a pre-completion test need to be re-evaluated because of a rating just below the limit for a fully finished construction.
