Acoustilyzer AL1  - 声学模拟音频分析仪

声学分析仪

 
The Acoustilyzer AL1 is the predecessor of the XL2 Audio and Acoustic Analyzer. It is a handheld sound level meter and acoustic analyzer for measuring and monitoring sound pressure level, room acoustics and, optionally, speech intelligibility STIPA. Additionally it offers basic audio measurements.

These acoustic and audio functions make the Acoustilyzer AL1 the ideal tool for measurement applications in Installations, Live Sound, Studio and Broadcast. The AL1 requires the optional measurement microphone MiniSPL for acquiring acoustical signals.
 

Features

 
Acoustilyzer AL1屏幕SPL
 

Sound Level Meter

In addition to the familiar instantaneous and integrated sound pressure level (SPL) measurements, the repeatable LEQ and LCpeak measurements complete the event monitoring requirements. The AL1 visualizes the actual audio spectrum (RTA) without interrupting ongoing sound level measurements. All measurement results may be logged to the internal memory for further investigations.
 
 

Acoustilyzer AL1屏幕RTA
 

RTA, Real Time Analyzer

The enhanced real time spectrum analyzer (RTA) features high speed measurements with selectable 1/1 and 1/3 octave bandwidth. The RTA simultaneously provides real time single band SPL and LEQ measurements complying with IEC 60804. Stored spectra may be averaged or combined by using the available mathematical functions. The “Max-Min” display is particularly helpful for finding dominant room modes and characterization of listening areas.
 
 

Acoustilyzer AL1屏幕FFT
 

Zoom FFT

The AL1 offers a fast, real-time Zoom FFT with resolutions up to 0.7 Hz over the entire frequency range. This is the ideal tool for visualization of comb filters and narrow band effects. Features further include detailed cursor readout and data storage.
 
 

Acoustilyzer AL1屏幕RT60启示时间
 

RT60, Reverberation Time

Reverberation time is measured in accordance with ISO3382 in octave audio bands (8 bands from 63 Hz to 8 kHz), including smart trigger and ranging features. The RT60 measurement with 1/3 octave resolution is supported by post processing. The test result reliability is displayed with confidence indicators. Suitable gated pink noise sequences are included in the Minirator MR-PRO and on the supplied Test-CD.
 
 

Acoustilyzer AL1屏幕延迟
 

Delay Time

The propagation delay time measurement for speaker setups is conducted between the electrical input of the AL1 and the built-in microphone. Automatic difference calculation simplifies the verification of correct delay arrangements for larger halls and auditoriums. A designated chirp is provided by the Minirator MR-PRO or the supplied Test-CD.

Electrical Measurement Functions

Besides the polarity verification for speakers and systems the AL1 includes basic electrical functions like Level RMS and distortion (THD+N) measurement. Unique smart features, like the "Balance indicator" (immediately showing balanced / unbalanced problems of the connected signals), support fast debugging of audio systems.
 
 

Acoustilyzer AL1屏幕STIPA
 

Speech Intelligibility STIPA (optional)

STIPA分析仪选件可在15秒(典型值)内实现持久可靠的语音清晰度测量。除单值STI或CIS测试结果外,还提供了调制指数和个别频段级别结果的详细视图。STIPA分析仪包括符合2003 IEC 60268-16标准版本的幅度加权。

指定的STIPA测试信号由Minirator MR-PRO或提供的Test-CD提供。

采集的测量值可以参考先前建立的背景噪声电平的图谱,并自动重新计算STI值。
