Sound Intensity Modul

  • Spatially accurate virtual measurement positions
    without time-consuming measuring by hand
  • Flexible adaptation of the standard-compliant test setup to the measurement conditions
  • Independent of the size of the measuring object
  • Visual representation of the measurement results in the form of a sound field map directly on the measurement object

Coordinate Viewer

  • Input of the measuring positions as X, Y, Z coordinates in Excel
  • The position data is transmitted to the augmented reality glasses and displayed spatially
  • Individual labeling of the measuring points
  • Recalling the measurement setup of an already performed measurement

Fragen und Antworten

The AR solution consists of augmented reality glasses (HoloLens 2 from Microsoft), the software platform „Sound HUB“ and individual modules with which the Sound HUB can be expanded as needed.

The Sound Intensity Module allows sound intensity measurements to be performed at discrete measurement positions according to DIN EN ISO 9614 1 and using a scan path according to DIN EN ISO 9614-3.

The Excel Coordinate Viewer module also allows measurements according to the DIN EN ISO 374x series of standards, as the measurement positions can be selected individually. However, standard-independent measurement setups and factory-internal ones can also be configured without any problems. This makes the Excel Coordinate Viewer extremely versatile.

  • Time savings of up to 80 % compared to conventional measuring methods due to visualization of the measurement setup
  • The measurement positions no longer have to be measured by hand
  • No auxiliary constructions influencing the physical and sound field
  • Measurement of objects of almost any size possible
  • Fast repetition of a measurement with the same test setup
  • Measurement information is visible through the AR glasses where it is needed, instead of only on the stationary measurement computer
  • Simple interpretation of results, as the results are made visible directly where they were also measured

The deviation of the test setup (enveloping surface) is less than 1 cm / m.

Module 1: Sound Intensity

The central object of the Sound Intensity Module is the display of a virtual test setup, which is displayed by data glasses. After entering the dimensions of the test object, the goggles automatically calculate the standard-compliant measurement positions in a matter of seconds. The time-consuming measurement of the measuring positions is now a thing of the past. Once the measurement is complete, the results can be displayed directly on the test object using a sound field map.

The Sound HUB in combination with the Sound Intensity Module is ideally suited for almost all areas of technical acoustics:

  • Sound intensity and sound power measurements according to standard series 9614 1 and 3
  • Machine acoustic investigations
  • Detection of acoustic leaks and development of countermeasures

Module 2: Excel Coordinate Viewer

The Excel Coordinate Viewer module makes it possible to display measurement positions in space with just one click. For this purpose, these positions are entered into an Excel spreadsheet in the form of simple X,Y,Z coordinates. By clicking on the HoloMetrix button, these are sent to the HoloLens 2 via Bluetooth.

The AR glasses receive the position data and automatically display them in space. The measurement points are aligned with a local target (coordinate system), which is placed near the measurement location. This enables fast and precise measurement preparation.

The AR solution can be used indoors, in acoustic rooms as well as outdoors (protect from moisture – rain / fog!). The HoloLens 2 scans the environment and orients itself to concise points. The more points there are for orientation, the more accurate the display of the measurement grid and thus the measurement itself.

We would be happy to present our solution to you personally and without obligation.

Measurement as a service

  • Determination of the current acoustic condition of your products
  • Derivation of technical and economically reasonable solutions 
  • Measurement at your site with our own equipment
  • Ensure that your products comply with regulatory requirements
  • You will receive the measurement results as fast as possible:
    For the measurement, we use our augmented reality software, which allows us to
    to perform the measurement without long preparation times.

Preparing a sound power measurement can easily take a whole day. With HoloMetrix's solution, it is much faster and more reliable. I was able to experience the solution live during a presentation on site in the laboratory and was impressed.

Honoured with the German Innovation Award in “Gold”

The company excelled in the “Excellence in Business to Business” competition class in the “Machines & Engineering” category with the “HoloMetrix –Sound HUB”, a positioning aid that significantly simplifies acoustic measurements using augmented reality. In AR glasses, a virtual experimental set-up is presented three-dimensionally in the real environment. This approach eliminates the time-consuming and tedious manual determination of the measuring positions.
This is a significant step forward from the usual procedures offering an impressive demonstration of what measurement will look like in the future,” according to the jury’s statement.
