Instruments for Noise
& Vibration Work for Windows™
vibration measurement software!
Analyzing noise and
vibration data can be difficult. It’s not often easy to see the
patterns or recognize the nuances of complex data sets. Furthermore,
presenting data in a way that is meaningful can be challenging, yet
perhaps our most important task.
Noise Work makes maneuvering through extensive data a
simple operation and putting together meaningful reports has never
been easier. Some of Noise Work’s many features include:
- Windows 98 ™/NT™
/2000/ XP setup
and control of Larson Davis Models 712, 720, 812, 814, 820, 824, 870B, 2800,
2900, 3200, HVM100, Ono Sokki DS2000,Ono Sokki CF3200-3400 &
Cortex NC10, SINUS Soundbook™
- Multiple live data displays
on the PC screen.
- Stream data directly from
analyzer to PC hard drive, including sound files.
- Read stored data files from
analyzer or disk.
- Create report templates for
easy graphing and printing.
- Organize templates,
graphics, and measurements for easy recall.
- Reports can integrate text,
graphics, pictures, or embedded objects (OLE 2.0) such as MS Word™, MS
Excel™, and .WAV files.
- Graph 1/1, 1/3, 1/12, 1/24
octave, FFT and zoom FFT, SLM parameters; statistical distribution and more!
- Cursor synchronization
between different types of graphics with ‘drag and drop’ functionality.

One Software Package for Unlimited
Noise Work was developed to
integrate and fully support all types of measurements made with Larson Davis’
noise and vibration instrumentation. It replaces the need for several different
software applications to achieve what you really want–display, analysis, and
reporting of all project measurement data. Noise
Work quickly produces high quality charts, reports, and presentations.
Real-time Display Mode
Noise Work displays and controls
measurement data on a PC in real-time, while maintaining access to all of the
instrument’s measurement and analysis functions.
Noise Work is “What You See Is
What You Get” software. You place, resize, and manipulate graphical objects,
images, graphs, text, and other types of objects on a page. What you see
displayed on the screen remains unchanged on the printed report.
Noise Work software interfaces with the Larson
Davis Models 812, 814, 820, 824, 870B, 2800, 2900, 3200, SINUS Soundbook™
Noise Work saves all
measurement-related files as elements of a project file. Project files can
contain measurement data, page descriptions, images, audio files, etc. All data
are organized in a tree structure (like Windows Explorer™). In addition, Noise
allows you to drag & drop any object onto project reports.
It is possible to perform any
kind of graphic presentation with dimensions, scaling, dotted lines, bar graphs,
overlaying, linear and log scales, EU, cursor synchronized among the graphics
displayed, etc. Any combination of graphs and objects (even an entire document)
can be saved as a template. In addition, you can perform cumulative distribution
versus time and for each frequency band, percentile Ln versus time and frequency;
frequency versus time, speed, distance or rpm; order analysis, RT-60, etc.
Noise Work calculates functions
including all mathematical operations from data blocks, spectra, multi-spectra,
levels versus time, engine revolution or speed, and more. Levels of selected
spectral bands can be modified or cancelled, both in frequency and in time
domain, for data matrix or multi-spectra. Several weighting curves are included
with the software.
Noise Work can be expanded to meet
your measurement needs with the following modules:
PC Direct Store
- Stores data directly to a
PC’s hard drive
- Intended for applications
where instrument memory is not sufficient, e.g. environmental monitoring,
passby’s, and long run-up
- Stores time domain signal
from the instrument to the PC sound card, and then to the hard drive
- Sound file can be attached
to a graph or page
- Creates “.WAV” files
Order Tracking Analysis
- Graphics template for order
- Spectrum vs RPM or Speed for
frequency or order
- RT-60 with backward
- ISO R140 & ISO 717
- ASTM E90-E336 & ASTM
- Support for ISO 9614
- Contour plotting (planar
- Overlay on DXF Autocad file
of the measurement surface
