 noiseLAB
Multi-channel Noise Acquisition & Analyzing System

 Now noiseLAB will go anywhere in the field fully powered by a laptop!!

 It's a portable sound level meter (1 to 8 channels),
a portable instrumentation tape recorder,
a 1/1 to 1/24 octave analyzer, and
an FFT analyzer up to 100,000 lines!

 

 

  • Digital Recording of up to 8 channels of acoustical signals on your computer: Now your laptop becomes your portable instrumentation recorder. You are only limited by your disk drive size, and can also use external disk drives.
     
  • Data Editing: Easy editing of your data to select the relevant signals of interest. Listen to and edit one or all channels simultaneously. Create an unlimited number of clips.
     
  • Sound Level and Statistical analysis: With just one mouse click, you measure the Sound Levels, Leq, SEL, and LN values of each clip and all clips combined.
     
  • Octave Analysis: from 1/1 to 1/24 Octave analysis.
     
  • FFT Analysis: Up to 100,000 lines FFT analysis. Just enter your Resolution, and measure.
     
  • Automatic Pass-by Noise Measurements: With one mouse click, noiseLAB grabs the 1/N Octave spectrum at the time of the Maximum Fast Sound Level.
     
  • Automatic Background noise correction: All measurements (sound level, FFT, or octave) automatically corrected for background noise.
     
  • Automatic Web Report Generation: Creates an HTML file with just one mouse click. Also export to Word and Excel.
     
  • Customize your reports using XML: Or for less advanced users, do all your formatting with traditional Word functions.
     
  • Calibration traceability: Your calibration data follows you through the entire process, including editing, post-processing and report generation.
     
  • Conformance to the latest Standards: IEC 61672-2 Sound Level meters Type 1and IEC 61260 Octave Filters Class 1 when used with corresponding microphones and hardware.
