For the realization of acoustic listening tests and research in the traffic environment, the institute possesses one specifically for this application adapted laboratory. The laboratory consists of a monitoring room and a via window connected acoustical dead room.
The acoustical dead room (according to EBU Tech. 3276, ITU-R BS. 775 und ITU-R BS. 1116-1
) allows to simulate free-field sound conditions and to perform hearing tests realistically under laboratory conditions.
Facilities of the laboratory
Devices for conducting hearing tests and measuring of subjective and physiological data (e.g. hand-dynamometer)
Two digital binaural artificial heads (HEAD acoustics® - HSU III.2)
Mobile recording and playback system (HEAD acoustics® - SQuadriga II)
Analysis software for the entire range of the signal, noise and vibration analysis (HEAD acoustics® - ArtemiS Suite)
Manual Sound Level Meter (Larson-Davis 824)
Actigraph with heart rate chest strap (Actigraph, LLC - wActiSleep-BT)
Measuring Devices for Traffic Analysis
Measurement trailer with a mast (12m high) including the video detection system Autoscope SoloPro for traffic data measurements (volume, density, speed)
2 mobile video detection systems Autoscope SoloPro for traffic data measurements
Automatic number plate recognition system (ANPR) with 8 detection cameras (4 cameras of type PIPS Technology P362, 4 cameras of type PIPS Technology P372)
10 GPS data logger QSTARZ BT-Q1000eX for recording driving cycles and speed distributions
2 high-precision GPS data logger for recording driving dynmics (1 Racelogic VideoBOX with video detection, 1 Racelogic VBOX3i with acceleration sensor)
2 traffic detection devices Sierzega SR4 for local traffic measurements
