Question:

Can you tell me how to setup and use the buttons on my G.R.A.S intensity probe in Simcenter Testlab Sound Intensity Testing?

Answer:

The process depends on which G.R.A.S intensity probe you are using to perform measurements. G.R.A.S is a manufacturer of microphones, intensity probes, and other acoustic products (www.gras.dk).

There are two models of G.R.A.S intensity probes 50AI-D (Two Button Probe) and 50AI-L (Four Button Probe) supported by Simcenter Testlab Sound Intensity Testing:

  • First you edit a INI file (*.ini) that is located in the following directory: C:\Program Files (x86)\Simcenter\Testlab {version}\central\Configuration per the default installation.

  • After navigating to the correct directory cited above open the ‘SoundIntensity.ini’ file. Lines with a # sound are comments and not read.  Under [Intensity Probe], remove the # sign (i.e., uncomment) for 'Type' and 'Port' as shown.

  • With ‘Type’ parameter is set to ‘G.R.A.S 50AI-D’, check for the correct Port setting in Device Manager. To quickly access the device manager use the MS ‘Search Windows’ function.

  • In Device Manager, look under "Ports (COM & LPT)".  When the Probe is plugged in via USB (or use a Serial to USB adaptor if needed) to the computer, a COM port entry should appear as shown.  The entry should appear/disappear as the probe is plugged/uplugged. The actual COM number will vary depending on availability.
