  • Airborne, impact and facade sound insulation

Overview

Sound Insulation is the measurement of the influence that a partition (usually a wall or ceiling) has on sound; in other words, how efficiently a partition insulates the sound between rooms. To evaluate this, a reference sound signal is generated in the sending room, and the noise spectrum is measured in both the sending and the receiving room. Additionally a room correction of the receiving room is applied based on the measurement of the reverberation time RT60.

The PA3 Power Amplifier, with built-in noise generator, provides the test signal. Played through the light-weight DS3 Dodecahedron Speaker, an omni-directional, flat acoustic frequency spectrum is produced. This spectrum and the reverberation time are measured by the XL2 Sound Level Meter. The measurement data is then imported into the Sound Insulation Reporter PC-software and all the standard sound insulation reports are created.

Advantages

  • Calibrated acoustic measurement system for traceable measurements
  • Lightweight omnidirectional sound source with building acoustics amplifier
  • Parallel measurements in sending and receiving rooms using Wi-Fi communication

PA3 Power Amplifier

PA3
The portable PA3 Power Amplifier contains a DSP-based signal generator with equalizer. In conjunction with the DS3 Dodecahedron Loudspeaker, a pink noise is produced with an acoustically flat frequency response. A test signal optimized for maximum sound power is available as well as an external audio input socket. All operating components are positioned on the sloping sides of the amplifier and illuminated, and are thus easily recognizable and accessible from a standing position.

For low-frequency measurements, an active subwoofer can also be connected. The test signal can be switched on and off from outside the measuring room with the push of a button on the supplied radio remote control.

XL2サウンドレベルメータ

XL2 with M4260 Measurement Microphone

リアルタイムアナライザRTA

リアルタイムアナライザは、周波数帯域ごとに遮音特性を評価するため、スペクトル特性を測定します。遮音特性は、異なる位置において1/1または1/3オクターブバンド解像度で測定されます。平均化された測定値により、遮音特性が一つのインデックスとして求められます。
 

RT60 残響時間

室間のレベル差は、受音室側の残響時間の影響を補正する必要があります。残響時間の測定は、反復測定用にオートトリガ機能が装備されています。音源としてインパルス信号やピンクノイズが使用されます。

型式承認オプション

遮音性能評価レポーター

XL2 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 for all measurement positions.

Additionally the software offers remote measurements; two or more XL2 Sound Level Meters may be controlled directly by the software connected via USB or wireless. This offers parallel measurements of sending and receiving room onsite, thus a great time saving.

The Sound Insulation Option enables the import of measurement data into the XL2 Sound Insulation Reporter software. Utilizing the new remote sound insulation measurement functionality requires an activated remote measurement option on the connected XL2s.

Sound Insulation Option

In order to import data from your XL2 Acoustic Analyzer to the Sound Insulation Reporter PC-Software, the Sound Insulation Option needs to be purchased and installed on each XL2 Analyzer that will use it. Data which has been recorded prior the installation of the Sound Insulation Option may then also be imported. The Sound Insulation Reporter software can then be installed on an unlimited number of computers in order to analyze this imported data.

Sound Insulation Reporter 365

An annual subscription service is offered as an alternative to the Sound Insulation Option. The purchase of a Sound Insulation Reporter 365 subscription allows the unlimited import of measurement data from one XL2 Acoustic Analyzer into the Sound Insulation PC-Software for a period of one year.

Multiple Installation

The Sound Insulation Reporter software can be installed on multiple computers. This provides consultants with the freedom to distribute their measurement projects among team members and clients.

Technical Requirements

The software is compatible with Windows Vista, 7, 8.x, 10. The full software functionality is enabled by having the following options installed in the XL2 Sound Level Meter:

  • Extended Acoustic Pack
  • Remote Measurement Option
  • Sound Insulation Reporter Option or Sound Insulation 365
