Octave Analyzer

Troubleshoot acoustics problems with seamless integration with data acquisition frontends

The LMS Test.Xpress Octave Analyzer is ideal for troubleshooting acoustic problems. The octave filter functions can be averaged or tracked against a specific channel. You can calculate all basic sound level meter functionalities (such as sound pressure level, Leq, SEL, Lpeak or Ln) with the different acoustical weighting and time constants in parallel. To simultaneously perform various analyses, you can combine the octave analysis with any other analyzer function. Additionally, the reverberation time measurements (T60) serve as base for qualification according to ISO standards such as ISO 140, ISO 354 and ISO 717.

The Octave Analyzer is seamlessly integrated with LMS SCADAS Mobile data acquisition frontends. LMS SCADAS frontends enable the silent operation required for acoustic testing since they do not have a cooling fan.
