noiseLAB 4.0: Even simpler, even more powerful

noiselab 4.0 provides professional noise measurement software to Type 1 standards that is

Simple

  • Easy to Learn
  • Easy to Use

A first time user can learn the basics in a few minutes by following the tips in this two-minute YouTube video.

The design of noiseLAB is user-driven, with dozens of features requested by advanced, professional users to give a faster, simpler workflow.

But this simplicity is also extremely

Powerful

  • 1/N octave, FFT Analysis, Sound and Vibration level with statistics.
  • Automatic Tone Analysis
  • Sound Quality Metrics
  • Automatic Impulse analysis
  • Vibration Analysis
  • Time Slice analysis

Perhaps most important of all, is the “secret” workflow that gives you

Better Results

noiseLAB gives you more accurate, better documented results because

  1. You can audit your recordings by
    • Listening
    • “Scrubbing” the files (viewing spectra while dragging the cursor through the waveform)
    • Editing the files to select the relevant part of the signal and exclude unwanted signals such as barking dogs or chirping birds.
  2. You can always go back to the original recordings to
    • Make another analysis on the same data
    • Verify the correctness of your data selection
    • Correct mistakes

This workflow of Record, Edit, Analyze gives better results with better documentation and gives you a stronger case should your measurements be challenged.

Fast Reporting

Results of all analysis types can be saved in Excel friendly form and also as fully annotated graphs in jpg format.

For example, with Slice analysis, you can Slice a signal into equal duration blocks, each one second long (user-defined duration).  With a single button you can generate annotated jpg graphs of all the slices, as seen in this Windows Explorer screenshot.

SlicesWindowsExplorer

Note that the file names contain the Slice number and actual start/end times, making it easy to find the relevant files without opening them.

And each jpg screen shot in automatically annotated with the most important documentation, thus reducing errors such as pasting a wrong graph into Word, or using a wrong Figure title:

frank Slice#42 41.000 to 42.000 s REC_Car Washing Machine

All of this, with a single mouse click.

As your experience with noiseLAB grows you will find even more features that make the product fast, fun, and powerful to work with.

The flexibility of noiseLAB Pro 4.0

noiseLAB 4.0 Data Flow

noiseLAB 4.0 consists of two programs

  • “noiseLAB Capture” for data acquisition, recording, and Editing
  • “noiseLAB Batch” for analysis of large batches of Recordings or edited Clips.

noiseLAB uses open data formats and can interface to a wide range of data types.

Inputs:

noiseLAB Capture accepts waveforms from:

  • National Instruments DSA Digitizers with IEPE transducer powering. This gives you plug-and-play configuration and a fully documented signal path.
  • Internal and external sound cards
  • .wav files from hard disk recorders, sound level meters, and other sources.
  • TDMS waveform files recorded by noiseLAB itself, or noiseLAB Wind. This gives you flexibility in analyzing files from other noiseLAB projects or noiseLAB Wind Recordings.

noiseLAB Capture can export waveforms in:

  • TMDS waveform format, with complete metadata annotation.  These files can be read by LabVIEW, Excel Plugins and others packages.  The format is fully documented by National Instruments.
  • .wav files.  Recordings or Clips from noiseLAB Capture can be output in scaled format to optimize dynamic range of the resulting files. The relative level of the individual files is retained.

noiseLAB Batch provides for advanced analysis (FFT, Octave, Tone or Impulse Analysis, Sound Quality, Vibration etc.) of multiple Recordings or Clips. Input data sources include:

  • Recordings from noiseLAB Capture
  • Recordings from noiseLAB 3.0
  • FFT Spectra for subsequent IEC 1996 Tone Analysis from
    • Delimited FFT files in a variety of formats
    • from noiseLAB 3.0
    • from noiseLAB Batch 4.0
    • noiseLAB Wind

noiseLAB Batch can output results as:

  • Tables of Results for each analysis type in delimited format easily parsed by Excel or other applictions.
  • jpg graphs of the result(s). For Time Slice analysis, graphs of multiple slices are automatically output in one operation.

This flexibility means noiseLAB makes it possible for you to interface to virtually any source of signals and output data in a range of popular and open formats.

noiseLAB 4.0 Release Candidate 3 available

Release candidate 3 of noiseLAB 4.0 is now available. It consists of two downloads:

  • noiseLAB Capture for wave file import, data acquisition, and editing of sound files.
  • noiseLAB Batch Processor for advanced analysis of files from noiseLAB Capture. Includes vibration analysis and sound quality metrics.

These Release Candidates will be subjected to certification testing, and when completed  will officially be released.

The products reflect extensive testing and performance improvements.

Important compatibility notes (only relevant for users who have used previous Release Candidates RC01 and RC02):

  • RC03 sound files and project files are not compatible with earlier release candidates.
  • Therefore if you want to keep these files, move the main folder containing earlier projects to a different location or rename it.  Otherwise you existing files may be overwritten.
  • To be able to process these files, you should not uninstall RC02.

The Release Candidates contain the full functionality of the full edition of noiseLAB and Expire October 31, 2014.

The files are available for download here

noiseLAB Release Candidate 2 Available

Updated April 29, 2014

The new noiseLAB Pro Family consists of two programs:

  • noiseLAB Capture for Data Acquisition, wave import, editing, and basic signal analysis.
  • noiseLAB Batch for advanced analysis, including tone and impulse analysis, psychoacoustic metrics, and vibration.

The release candidates (RC2) for noiseLAB Capture and noiseLAB Batch are now available for download.

The preliminary Users Guide is available noiseLAB 4.0 Users Guide0.8

CaptureInputSection

  • noiseLAB Capture RC02 is not compatible with previous versions of noiseLAB Capture or noiseLAB Express.
  • noiseLAB Batch RC02 is compatbile with noiseLAB 3.0.17 (.nlp project files) and with noiseLAB Capture RC02 (.nlrc project files)

For best performance we recommend Windows 7 or above with 8 GByte RAM og 256 M Solid Stateddisk.  However, the programs will run on Windows XP Service Pack 2 through Windows 8.  Loading and performance will be slower on older machines.

Extensive online help is available by clicking or right clicking on the DELTA Logo and ? in the upper right corner of the screen.

You can download the Release Candidates from here.

The new noiseLAB Programs will be numbered as version 4.0

We welcome your feedback and questions at noiselab@delta.dk

Major new features in noiseLAB Pro

noiseLAB Pro is a major upgrade of noiseLAB with greatly improved usability and new measurement functions.

noiseLAB provides a completely re-designed front end for one-click import, calibration and editing, plus support of a wider range of National Instruments data acquisition devices.

Load and editing performance for long files is significantly improved.

“Scrubbing” lets you view the FFT or octave spectra while dragging your cursor through the waveform.

Editing is performed with a single click-drag-release gesture, and can be fine tuned using numerical entry. Created Clips can be renamed and measurement annotation can be added, including links to picture or video files.  Each Clip is clearly indicated on screen in the associated recording.TotalFP with Clips

Increased dynamic range of the built in volume control overcomes the limitations of Windows native volume control, letting you listen to signals from low level wind turbine noise, to high volume jet engines.

New measurement functions in the associated Batch Processor will include vibration, Sound Quality, and the Joint Nordic Impulse method.

noiseLAB Pro is compatible with Windows XP Service Pack 2 through Windows 8.

An overview of the entire noiseLAB Family is available here.
