Test Solution for Building Acoustics

Building Acoustics Solutions

The XL2 Building Acoustics Kit consists of the XL2 Sound Level Meter, omnidirectional DS3 Dodecahedron Speaker, PA3 Power Amplifier, and Sound Insulation Reporter PC-software. These provide professional airborne, impact and facade sound insulation measurements in accordance with the standards.

Measurement of Sound Insulation in Buildings and of Building Elements

The portable XL2 Building Acoustics Kit is ideally suited for use on site. With only 7.5 kg and a typical sound power of 120.5 dB, the DS3 Dodecahedron Speaker is built for use on construction sites. The DS3 delivers an omnidirectional sound with a flat acoustic frequency response. The XL2 Sound Level Meter measures the noise spectrum in the sending and receiving room as well as the reverberation time.

The standard-compliant measurement report can be generated immediately on site using the Sound Insulation Reporter PC software.

Advantages

  • Calibrated acoustic system for traceable measurements
  • Lightweight omnidirectional sound source with amplifier
  • Simultaneous measurements in sending and receiving rooms using Wi-Fi communication
  • Supports ISO 16283, ISO 140, ISO 717, ISO 10140, DIN 4109, BB93, Document E, ASTM E336, ASTM E413, ASTM E1007, ASTM E989, ASTM E966, ASTM E1332, GB/T 19889, and SIA 181 standards

Dodecahedron Speaker Set

DS3 Dodecahedron Speaker

The Dodecahedron Speaker Set offers a lightweight, yet powerful signal source for building acoustic measurements. The optimized frequency response ensures precise measurements in accordance with the ISO 16283 and the ISO 3382 standards. The set includes the robust omnidirectional DS3 Dodecahedron Speaker and the remote-controlled PA3 Power Amplifier.

The DS3 Dodecahedron Speaker, together with the PA3 Power Amplifier, meets all the requirements of the ISO 16283 standard. In addition, we offer impressive performance data; with a weight of only 7.5 kg and a typical sound power of 120.5 dB, the DS3 is convenient to carry around on site. By pressing a button on the supplied wireless remote control, the test signal can be comfortably switched on and off from outside the sending room.

  • Compact and lightweight 
  • Maximum sound power level 120.5 dB 
  • Wireless remote control

XL2 Analyzer for Building Acoustics

XL2

Spectrum Analyzer
The XL2 Sound Level Meter measures the noise spectrum in the sending and receiving room. The level difference forms the base of the sound insulation calculation. Additionally a background noise spectrum recorded in the receiving room (without the test signal) allows for a noise correction.

RT60 Reverberation Time
The level difference between two rooms needs to be corrected for any influence of the reverberation time in the receiving room. The reverberation time is measured by the XL2 in 1/1 octave resolution (or in 1/3 octave resolution with the optional XL2 Extended Acoustics Pack installed). The RT60 measurement offers automated triggering for repeated tests using an impulse or gated pink noise as signal source.

Sound Insulation Reporter Software

XL2

The Sound Insulation Reporter is a PC-based software application that provides all the standard reports for Airborne, Impact and Facade sound insulation measurements. Designed for acoustic consultants, this comprehensive tool uses data gathered by the XL2 Acoustic Analyzer, and quickly returns graphical analysis of all measurement positions.

Additionally, the software offers the ability to acquire real-time data; two or more XL2 Sound Level Meters may be controlled directly by the software. This allows simultaneous wireless measurement in both the sending and receiving room on site; saving time. To enable this real-time acquisition of data, the Sound Insulation Reporter software requires that the connected XL2s also have an activated Remote Measurement Option installed. The Sound Insulation Option enables the import of XL2 measurement data into the XL2 Sound Insulation Reporter software.

Features:

  • Airborne, impact and facade sound insulation
  • Parallel measurements in sending and receiving room
  • Standardized Reporting

Laboratory measurement of sound insulation of building elements according to ISO 10140

The XL2 Building Acoustics Kit offers also a professional solution for measurements in a test facility. The sound insulation measurement of construction materials according to ISO 10140 is fully supported. This makes it possible to compare the sound insulation properties of building components and to estimate the real-world behavior in the finished building. The measurements can be started remotely on the computer and evaluated in the Sound Insulation Reporter software. Also, the test signal on the DS3 Dodecahedron Speaker starts and stops automatically. In addition, the DS3 offers a reliably consistent output level over extended periods; it is ideally suited for extensive and precise measurements on the test bench.

TM3 Tapping Machine

XL2

The remote-controlled TM3 Tapping Machine is a precision impact noise source for building acoustic measurements. It is typically used for the assessment of general impacts in dwellings that occur on floors or stairs in a building, and can be operated autonomously, due to the built-in battery.

The Tapping Machine complies to the standards ISO 16283-2, ISO 717-2, ISO 10140-3/-4/-5, ISO 140-6/-7/-8, DIN 52210-6, ASTM E492 and ASTM E1007.

The Dodec kit is amazing and we love the feature with the separate subwoofer output! You’ve done a really good job with the cases and the carrying flexibility too, well done!

I Love It! The XL2 is currently the world’s most versatile hand-held acoustic and audio analyser. I can do so much with it, and just love it! And in many ways, the associated Data Explorer software is much more versatile and easier to use than other leading industry equivalents.

Very Simple to Use! I must say that the instrument and the software are brilliant, and very simple to use, even for an old fogey like me.
