SVAN 979 User Manual
1.1 SVAN 979 AS SOUND LEVEL METER & ANALYSER
• Noise measurements (Peak, Max, Min, Spl, Leq, SEL, Lden, LEPd, Ltm3, LTeq, Leq statistics (Ln),
expected Leq value (EX), standard Leq deviation (SD), two rolling Leq (LR1 and LR2), measurement
time and overload time % (OVL) as well as noise criterium (NC) and noise ratio (NR) in case of 1/1
Octave option) with Class 1 IEC 61672-1:2013 accuracy in the frequency range 3.15 Hz to 20 kHz with
the GRAS 40AE microphone.
• Parallel Impulse, Fast and Slow detectors for the measurements with A, B, C, G, Z frequency filters.
• Two measurement ranges 22 dB RMS(A) ÷ 123 dB Peak (Low) and 30 dB RMS(A) ÷ 140 dB Peak
(High).
• 1/1 Octave (15 filters with centre frequencies 1 Hz ÷16 kHz), 1/3 Octave (45 filters with centre
frequencies 0.8 Hz ÷ 20 kHz) and optional 1/6 Octave (90 filters with centre frequencies 0.73 Hz ÷
21.4 kHz) and 1/12 Octave (180 filters with centre frequencies 0.71 Hz ÷ 22 kHz) real time analysis, in
accordance with Class 1 IEC 61260-1:2014.
• STIPA (speech transmission index for public address systems) measurements of electro-acoustic and
acoustic environments effects that affect the speech intelligibility in the room acoustics and/or public
address systems.
• Optional reverberation time RT60 analysis function for 1/1 octave bands or 1/3 octave bands and three
total RMS levels (A, C and Z weighted) in accordance with the ISO 3382 standard.
• Optional Loudness and Tonality functions.
1.2 SVAN 979 AS VIBRATION LEVEL METER & ANALYSER
• General Vibration measurements (acceleration, velocity and displacement) meeting ISO 20816-1:2016
standard in the frequency range depending on the parameters of the attached accelerometer, i.e. with
SV 80 general purpose transducer is equal to 0.5 Hz ÷ 14 kHz.
• Parallel RMS, Max, Peak, Peak–Peak, MTVV measurements.
• Z, HP1, HP3, HP10, Vel1, Vel3, Vel10, VelMF, Dil1, Dil3, Dil10 and Wh weighting filters.
• 1/1 Octave (15 filters with centre frequencies 1 Hz ÷16 kHz), 1/3 Octave (45 filters with centre
frequencies 0.8 Hz ÷ 20 kHz) and optional 1/6 Octave (90 filters with centre frequencies 0.73 Hz ÷
21.4 kHz) and 1/12 Octave (180 filters with centre frequencies 0.71 Hz ÷ 22 kHz) real time analysis, in
accordance with Class 1 IEC 61260-1: 2014.
• Optional RPM measurement with the use of RPM probe, connected to the I/O socket of SVAN 979.
• FFT analysis with the single Total overall value, performed with preselected frequency weighting filters
and screens.
