SVAN 958A User Manual
1.1 SVAN 958A AS SOUND LEVEL METER & ANALYSER
• Noise measurements (SPL, LEQ, SEL, Lden, Ltm3, Ltm5 and statistics) with Class 1 accuracy (IEC 61672-
1:2013) in the frequency range 10 Hz ÷ 20 kHz (with the SV 22 microphone)
• Two measurement ranges (Low and High) with total range 24 dBA RMS ÷ 194 dBA Peak (for the
microphone with the sensitivity 50 mV/Pa)

• Simultaneous measurements in three profiles of any channel with the independent set of IMPULSE, FAST
and SLOW detectors with standard A, C, LIN and G filters
• Digital True RMS detector with Peak detection, resolution 0.1 dB, Time Constants: SLOW, FAST,
IMPULSE
• 1/1 Octave and 1/3 Octave real time analysis (optional) - fifteen 1/1-octave filters with the centre
frequencies from 1 Hz to 16 kHz and forty-five 1/3-octave filters with the centre frequencies from 0.8 Hz to
20 kHz, Class 1 - IEC 1260
• FFT real time analysis with up to 1920 lines in 22.4 kHz band with Hanning, Rectangle, Kaiser-Bessel or
Flat Top window (optional)
