Find the direction of reflecting surfaces relative to the microphone
If you need to quickly locate the direction and intensity of reflections in an acoustic environment, just use Polar ETC (PET) software with your TEF analyzer. Sound Lab Polar ETC (PET) software generates polar coordinate plots from ETC (Energy Time Curve) data. The result for the contractor and consultant is accurate and rapid distance and direction information regarding problem reflections.

The Sound Lab Polar ETC (PET) program not only measures the magnitude and time of arrival of reflections, but also reports the direction of the reflecting surface relative to the microphone placement. The software is supplied with a Mic Stand and Positioning Arm.

A total ETC (PET) setup is available as the SLPETKIT which includes the PET software, the Mic Stand and Positioning Arm, a Cardioid Mic, an Alignment Laser and a Hard Side Carry Case.

Time-saving accuracy
Sound Lab Polar ETC makes six ETC measurements with a cardioid microphone. These measurements are made while the microphone is sequentially pointed in the six axis of directions of a three-dimensional rectangular coordinate system. The Polar ETC data is calculated from these six measurements and the directional properties of the cardioid microphone. As the cursor is moved in time, the azimuth, elevation, SPL and distance are reported for that time of arrival.
