SVAN 957 Sound Level Analyzer

  Overview Using It Software Options Specifications  

Sound Level Analyzer

The SVAN 957 Sound Level Analyzer is a professional grade Sound Level Meter with real-time Octave Band Filters and data storage that suits most noise monitoring applications.

  • Occupational Noise - Control of Noise at Work
  • Environmental and community noise assessments
  • Room acoustics - reverberation time (option)


  • ANSI S1.4 Type 1, IEC 61672 Class 1, IEC 60804 & 60651 Type 1
  • Integrating Sound Level Meter - Leq, SEL, Lden, LEPd, Ln
  • Real-time Octave Band Filters
  • Measurement store and high-speed logging (down to 2ms)

Sound Level Analyzer SV957

This Type 1 Integrating Sound Level is ideal for any acoustic professional involved in occupational noise measurement (protection of hearing) or environmental and community noise surveys. The standard meters satisfies most applications as it includes the basic parameters such LAeq, LCpeak, Ln as well as real-time Octave Band Filters. It can be used as a simple hand-held meter for quick noise measurements, or the powerful timers and data logger can make more detailed analysis an easy task.

If you are involved in monitoring noisy neighbors, or have any other application where you need to listen to the actual sound, then the SVAN 957 has an option to record the audio. It is also available as part of a complete Noise Nuisance Recorder.

Occupational Noise Measurement
The SVAN 957 measures the all important LAeq (A-weighted Leq) and the LCPeak (C-Weighted Peak) for a basic noise survey. It can also measure the Octave Band Spectrum, which can be used for a details hearing protector assessment.

Community Noise Measurement
As well as the usual parameters provided by an Integrating Sound Level Meter, the SVAN 957 calculates the Ln values (L1, L5, L10, L90, L95, L99). It can easily be set to measure over timed periods (e.g. repeating 15-minute measurements) and can store a detailed time-history of the noise levels.
