Svantek 979 Class 1 sound and vibration level meter

The SVAN 979 is a top-class Class 1 sound level meter and analyser, renowned for its outstanding technical specifications. With a measuring range starting from just 12 dBA, this instrument is ideal for acoustic engineering applications, including sound insulation measurement and precise frequency or signal characteristic analysis.

The SVAN 979 features frequency analysis in 1/1 and 1/3 octave bands, FFT analysis and audio recording for identifying noise sources. In addition, the basic package includes a building acoustics kit with RT60 measurement and signal generator functionality. The high accuracy and extensive features of the SVAN 979 make it an indispensable instrument for detailed acoustic assessments and professional measurements.

Building acoustics for professionals

The SVAN 979 delivers highly accurate measurements with spectra logging at millisecond level, essential for assessing facade, airborne and impact sound insulation. Preset configurations and the Assistant PRO app streamline multi-point measurements and make it possible to operate the instrument and the sound source remotely.

Equipped with a signal generator for pink noise, white noise or sine waves, the SVAN 979 supports detailed acoustic testing. On-site RT60 verification is quick, with extensive calculations performed by the SvanPC++ Building Acoustics software.

The SVAN 979 excels in 1/1 and 1/3 octave frequency analysis and guarantees accurate RT60 and sound insulation results. The Building Acoustics PRO app guides users through the procedures and enhances reports with photos and descriptions that comply with the ISO 16283 standards.

The SVAN 979 also performs STIPA measurements, which is crucial for assessing speech intelligibility in public address systems and educational environments. This makes it an indispensable instrument for building acoustics professionals.

Applications

• STIPA measurements and calculations
  Supported by a dedicated mobile application in accordance with IEC 60268, ideal for measuring speech intelligibility in various environments such as auditoriums, schools and public spaces.
• RT 60 measurements
  Provides quick on-site verification of reverberation time (RT 60), which is crucial for evaluating the acoustics of concert halls, theatres and recording studios.
• Vibration measurements
  Can perform vibration measurements by simply connecting a vibration sensor. This is useful for industrial applications, such as monitoring machine vibration and structural vibration analysis.
• Real-time frequency analysis
  Performs frequency analysis in 1/1 octave, 1/3 octave spectra or FFT bands. This functionality is important for detailed acoustic analyses and sound quality studies.
• Infrasound analysis
  With an optional microphone and analysis options, it offers infrasound analysis from 3.15 Hz. Ideal for wind farms and other applications where low frequencies matter, such as measuring noise nuisance from large industrial installations.
• Sound insulation measurements
  Using the smartphone application and RT 60 functionality, it helps calculate sound insulation in accordance with ISO 16283, which is essential for building acoustics and sound insulation projects.
• WAV recording
  Ability to record the time domain signal in WAV format up to 48 kHz, with post-processing available in the SvanPC++ program. This is convenient for detailed sound analysis and documentation.
• Environmental monitoring
  The outdoor monitoring case (SM 279 PRO) and outdoor microphone protection kit (SA 279) make it suitable for long-term noise monitoring in outdoor environments, such as cities, nature reserves and construction sites.
