Measurement and analysis of sound and vibration




Applications

Signal acquisition and real-time analysis: The online display (real time) allows you to start your analysis during recording.

si++Workbench - Standardized Analyses

Over 200 common, easy-to-use analysis functions for sound and vibration. Clearly arranged work in three integrated interfaces: measurement, analysis, and documentation.

si++Expert System - analyses in a modular system

All analysis tools in a flexible, modular systemAll analysis functions can be individually combined and linked according to the work to be done. These links are saved as separate "analysis programs".

siCamera - optical/acoustic recording of sound intensity

Film camera for sound intensity distribution with a probe array (sound intensity camera).

siSoundpower - sound power measurement

Measurement of the sound power according to DIN/ISO standards using sound pressure.

siIntense - sound intensity measurement

Measurement of the sound intensity with the classic p-p probe and the new p-u probe.

siVision - sound design

Integrated analysis, filtering and noise rating. siVision optically displays what the ear perceives and makes it possible to filter disturbance and background separately. Psychoacoustic findings are implemented here in a user-friendly way.

siPass-by  - pass-by measurement

Pass-by measurement system according to ISO 362 with numerous analysis options such as high-resolution order analysis, tire rolling noise measurement and noise source separation.

siBuilding - architectural acoustics

Measuring system for determining the sound insulation for airborne and impact sound according to DIN/ISO 140. Analysis and reporting are integrated in a single interface.

siVoyager

From 1 to over 1000 channels: The right Voyager for everyone

si++Voyager stands for different data recording systems, from a small system in a briefcase to a large test rig with many channels. The operation is completely hardware-independent, clear and simple.

With modularity and future-proof designs, we continue to support all data recording hardware that we supply, with the latest and most convenient software interface as well. This gives you security and protects your investments for the future.

From 1 to over 1000 channels: Portable measuring technology from a single source

The requirements for a portable measuring system for sound and vibration signals can vary considerably. For this reason, Akustik Technologie Göttingen works together with several hardware partners in order to always provide you with the right portable measuring system: Besides special Solutions for 1-4 channels we offer the new Voyager Family beginning with Voyager 6 for 6 channels.

Use with a uniform user interface

No matter if you have a system with 2, 6, 24, 200 or more channels, a common feature is easy operation via the si++ software.

The Voyager user interface also gives you a choice: the si++Workbench interface for explorative data analysis or the si Workbench Taskmode orsiIntense, siVision, siPass-by, siBuilding, siEvent, siCamera, si++ExpertSystem and some special solutions.

It is no problem to work with any number of channels in different systems: The only difference in the user interface is the control of the front end and the type of channels present.

Naturally, every si++Voyager is a full-fledged system for analyzing sound and vibration signals and is in no way inferior to a laboratory system. However, you can also use your customary computer at work, if you prefer: a "floating license" can be used on several computers.

 

The entire range of sound and vibration analysis

The entire range of sound and vibration analysis modules from Akustik Technologie Göttingen are available to you on all models of the Voyager family.

View our Products and Applications for a detailed overview.

 

Data management

All analysis modules have the same project management: every measurement and analysis is at hand at all times. 

Do you want to make your data available to your coworkers through the company network or save your data in a network? The project management helps you with this as well.

 

Your results - on paper

You want to see the result of your work on paper now!
With si++, you can directly print out your results, export them to other applications (e.g.  Word®) via the Windows® clipboard or integrate them into layouts of your design. Designing a layout that contains your company logo, for example, is easy with the siReport. The positioning and scaling of the individual elements is precise to the millimeter here, the format is PDF. 

 

Compatibility

In si++ there is only one data format. Completely regardless of how many channels you record or what scanning rates you use. For this reason, the data generated with a Voyager is compatible with all other data.
In order for you to be able to work with other systems as well, there are numerous data converters from and to very different data formats.
