Advanced Analysis Capabilities
- Frequency analysis in discrete frequency (FFT), 1/3 octave, or full octave to look at frequency content
- Joint Time Frequency Analysis (JTFA) to see how the frequency content is changing over time
- Order analysis to find component signatures for rotating machinery
- Noise propagation modeling software to predict sound levels from facility changes or noise remediation techniques
- Frequency response analysis to determine a component's natural frequencies (impact hammer and operating frequency response)
