- Class 1 IEC 61672:2002 sound level measurements - General vibration measurements (acceleration, velocity and displacement) - Three parallel independent profiles - 1/1, 1/3 octave real-time analysis - FFT real-time analysis 1600 lines in up to 22.4 kHz band - Time-domain signal recording - Advanced data logger including spectra’s logging and Audio Events Recording - Reverberation Time measurements (RT60)

The SVAN 979 is “top of the range” Type 1 sound & vibration instruments and is designed to meet the needs of both environmental monitoring and occupational health and safety monitoring specialists. Its exceptional hardware design also enables the measurement of ultra sound frequencies in the 40 kHz band. The SVAN 979 provides broadband results with all the standard weighting filters and also offers an incredible time history logging capability providing broadband results and spectra with adjustable double (long and short) logging steps. Audio recording can be performed simultaneously with time history logging as either a separate wave file or as audio events inside time history files. This solution enables noise source recognition and data post-processing. Manual and automatic triggering of audio recording is also available. Measurement results are recorded in three acoustic or vibration profiles enabling measurements to be performed with 3 different filters (e.g. A, C, Z) and 3 different detector time constants (e.g. Fast, Slow, Impulse).
