DATA, NAVIGATION, ANALYSIS SOFTWARE

Analyzing noise and vibration data can be difficult. Its 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.

DNA (Data, Navigation, and Analysis) makes maneuvering through extensive data a simple operation and putting together meaningful reports has never been easier. Some of DNA’s many features include:

• Control of Larson Davis Models 831, SoundTrack LxT, HVM100, 720, 812, 820, 824, 2900B, & 3000+.
• 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 Microsoft Word, Microsoft Excel and WAV files.

FEATURES

Make any graphic presentation with dimensions, scaling, dotted lines, bar graphs, overlays, linear and log scales, and cursors synchronized between graphs. For repetitive tasks, create the ideal document and then save it as a template to easily reuse it with different data.

• Management of graphics, numerical tables, comments, dynamic markers, digital photos, and video clips
• Direct import of image files
• X, Y, and Z axis definable as linear or logrithmic with selectable values, or using autoscale
• Cut and paste between sequences acquired in the time domain
• Measurement recalibration and level modification in frequency and time domain
• Spectrograms and 3D graphics (waterfall)
• Mathematical functions, masks in time and frequency domain, automatic identification of the events, tonal components, etc
• Creation of the curve family as ISO-NR, ISO-2633, Isophonics ISO-226, etc
• Weighting curves
• Statistics on the overall value and per frequency band, also in FFT.

MEASUREMENT ORGANIZATION

DNA 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, DNA allows you to drag & drop any object onto project reports.

The dual view of the data allows for an immediate flip from graphical view to tabular view of the measurement or processing data. Using the F2 (graphical) or F4 (tabular) toggle, you can verify your measurement values or export them to Microsoft Excel for example.

DATA POST-PROCESSING

DNA 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 canceled, both in frequency and in time domain, for data matrix or multi-spectra. Several weighting curves are included with the software.

OPTIONAL MODULES

DNA can be expanded to meet your measurement needs with the following modules:

• Events tracking: PNL and PNLT event time history and EPNL event, TRAIN 6-22 and 22-6 processing
• 3D color mapping
• Optimized mapping using OpenGL, requires DNA Mapping
• Industrial Hygiene
• Building Acoustics, allows calculation of transmission loss and sound insulation calculations.
• Direct Store and File Audio option storing directly on a computer bypassing instrument memory
• Order tracking capabilities.

ARCHITECTURAL ACOUSTICS

The Architectural Acoustics module of DNA focuses on the sound transmission loss calculation according to ISO and ASTM standards.

• Reverberation Time (RT-60) data can be imported or tuned if the original decays per octave are available, including support for the backward Schroeder Integration method). Typical standards are ISO 3382-2, ISO 354
• Absorption Coefficient calculation based on ISO 354, 11654 or ASTM E2235
• ISO 140 & ISO 717 for adjacent rooms, building façade and floor transmission loss
• ASTM Standards E90,E336, E966, E492, E1007 and classification standards E413, E1332 and E989
• Leveraging the powerful DNA Graph Template concept, DNA allows you to plug your measured data directly in the appropriate template to go to the recommended graphical representation of the results. DNA will also average the transmitting, receiving or background levels.
