Octave and Third-Octave Band Ln Calculation Module for NoiseTools
Noise Analysis SoftwareThe Octave and Third-Octave Band Ln Calculation Module is an add-on for the NoiseTools software that allows you to calculate Ln values, such as L10, L50 & L90, in 1:1 and 1:3 Octave Bands.
- Calculate Ln values in 1:1 or 1:3 Octave Bands
- Process commonly used Ln values (L1, L5, L10, L50, L90, L95, L99) and add user-defined Ln values
- Choose from Unweighted, dB(A) or dB(C) frequency weightings to give Ln, LAn or LCn values in each frequency band
- View the calculated values in graphics & tabular formats and export into other applications

The Octave and Third-Octave Band Ln Calculation Module is an add-on for the NoiseTools software that allows you to calculate of Ln values, such as L10, L50 & L90, in 1:1 and 1:3 Octave Bands.
This allows, for example, L90 values in 1:3 octave bands from 100Hz to 5kHz to be calculated and used to assess the tonal content of a noise measurement.
Using time history data that has been downloaded from a suitable Optimus+ Industrial or Optimus+ Environmental Sound Level Meter, the module processes this information using the same statistical method used in the Optimus+ Environmental Sound Level Meters.
The module allows the calculations to be run on a pre-defined list of commonly used Ln values (L1, L5, L10, L50, L90, L95 & L99) and additional, user-defined values can be added if required.
In addition, dB(A) or dB(C) can be applied to the calculations (the default configuration uses applies no frequency weighting to the calculations).
Alongside the calculated Ln values in each band, the module can also display the overall Leq for each frequency band as well as the value of the highest sample used within each frequency band.
In addition, the overall broadband Leq (A, C or Z weighted) and LFmax (A, C or Z weighted) values can be displayed for reference and comparison purposes.
The calculated values are displayed both in graphical and numerical form and a report can be produced and these can be exported for use in other programs or applications as required.
Octave and Third-Octave Band Ln Calculation Module for NoiseTools
The Octave and Third-Octave Band Ln Calculation Module is an add-on for the NoiseTools software that allows you to calculate Ln values, such as L10, L50 & L90, in 1:1 and 1:3 Octave Bands.
The Ln Calculation module for NoiseTools allows you to:
The module allows a measurement report to be quickly generated which contains both the graphical and tabular data in a clear, straightforward layout.
This report can be saved, printed, or exported in a range of formats, allowing it to be incorporated into other reports or documents quickly and easily.
The graphical display can be saved as an image and the tabular data exported as either a CSV or XML file for use in other applications.
This Module is an add-on extension to the NoiseTools software.
