Test Solution for Building Acoustics

The Dodecahedron Speaker Kit 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 kit 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

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.

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 Extended Acoustics Pack installed). The measurement offers automated triggering for repeated tests using an impulse or gated pink noise as signal source.

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

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.

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.
