FlexPro Acoustics Option
Introduction
FlexPro's newly released Acoustics Option performs accurate sound level and sound power computations.
In one easy and automatic step, you can effortlessly characterise multiple channels of sound data. In order to optimally estimate sound levels and power, FlexPro's innovative visual Analysis Wizard offers real-time 2D and 3D graphs and true interactive numerics. Acoustic analysis has never been this easy!
Calibrations made easy
To obtain accurate sound levels, a calibration must be performed. You may either specify a fixed calibration value or let FlexPro calculate the value from a calibration signal recorded with the calibrator attached to the microphone. You may do an automatic calibration by attaching a calibrator to the microphone prior to the measurement for a few seconds and then continue with your measurement.
Compute accurate octave analysis in time domain
An octave analysis based on FFT methods will often lead to
incorrect results. This is especially true at low frequencies. For most
acoustic applications, it is thus necessary to compute octave analysis
using time domain filters. With FlexPro's Analysis Wizard you easily
set the frequency range and resolution. The Wizard builds a complete
report with just a couple of mouse clicks.
Features
- Sound power computation including all correction terms for barometric pressure and temperature (K0), background noise (K1), environmental correction (K2) and enveloping surface (Ls).
- Sound level evaluation: Frequency weighting Linear, A, B, C. Time weighting Fast, Slow, Impulse Leq, Peak. Results may be level versus time or last level. Easy calibration support.
- Octave analysis using time domain filters: Resolution octave, third octave and 1/6, 1/12 and 1/24 octave. Frequency weighting of result may be Linear, A, B, C.
