XL2 測定用ファンクション

XL2 with M4260 Measurement Microphone

音声明瞭度 STIPA

信号ソースにTalkBoxを使用し会議システムの音声明瞭度を測定。

 

リアルタイムアナライザ RTA

Fine tuning the system performance with pink noise at each seating position. The reference spectra of speakers may be captured for comparative measurements, thus achieving the same sound performance of all speakers.
 

音圧レベル SPL

ベストパフォーマンスを得るための音圧レベル設定。
 

遮音特性

XL2は、室間及び室内外の遮音特性を測定します。足音などの衝撃音の遮音特性は、タッピングマシンを使用して測定されます。室間のレベル差は、受音室側の暗騒音の影響を補正する必要があります。
 

RT60 残響時間

室内構造の検証と改善に応用、機器のパフォーマンスと音声明瞭度を最適化。
 

FFT 解析

反射と打消し(くし型フィルタ効果)を解析、室内構造と音声明瞭度を改善。
 

NC曲線

Measure the spectral distribution of the ambient noise with the optional Noise Curve function to verify if the noise criteria requirements are met.

ワン、ツー、テスト

Talkbox on Stand

You may hear installation engineers repeating the phrase "test, one, two" while setting up microphones. They are not practicing counting; they are checking the frequency response of the microphone. The "uhn" sound of the word "one" produces a low vocal frequency, while the ‘t’ sound in ‘two’ produces a high vocal frequency. (Counting "three, four" adds no more value except perhaps to demonstrate that we installation engineers can, in fact, count past two.)

The NTi Audio TalkBox simplifies and improves the setup of microphones by generating a reference human speech signal or other standard audio test signals, so that all frequencies (not just the frequencies produced by "one, two") can be efficiently adjusted by a single person.

The TalkBox generates all test signals for professional conference room commissioning. Simply position the TalkBox at each speaking position.


Speech intelligibility STIPA

The NTi Audio TalkBox generates the speech intelligibility test signal into the talker's microphone for STIPA measurements with the XL2 Analyzer.
