Vibration and ground borne noise - rail traffic
A solely theoretical prognosis of vibrations and groundborne noise for railway tracks is often insufficient, especially in tunnels. This is due to various uncertainties such as the dynamic behavior of the tunnel, the underground structure of affected buildings and the resulting interactions, which cannot be simulated accurately by theoretical models. In order to obtain reliable prognoses, experimentally substantiated investigations of the vibration transfer are essential prior to the construction of new railway tracks. Based on the prognosis, immission protection measures for the affected population can be taken if necessary. An ideal source of synthetic vibrations is a strong vibrator which is designed to simulate vibrations in the right frequencies and intensities. With these experimentally based data, the ideal vibration protection system can be adjusted for individual spots.
VibroScan.at (Vibrator)
The VibroScan.at (advanced technology) method is a further development of the already established VibroScan method wich was developed by us earlier.The method alows to simulate vibrations to define vibration forcasts.
Prof. Dr. Peter Steinhauser is holding utility patents in Autria and Germany for the VibroScan method.

Vibration and ground-borne noise - road traffic
Road traffic can cause an unacceptable level of vibrations as well, although these immissions are often lower than those caused by trains. Before the road is built, a vibrational investigation helps minimize the resulting discomfort.
Site vibrations
Since the vibration sources mentioned above are limited to transportation routes, problems around building sites can emerge in residential areas. The occupants often fear vibration-induced damage of their homes. The propagation of vibrations can be analysed and minimised in advance, it is also possible to limit site vibrations with continuous control and alert systems (SMS, e-mail, lights,...)
Environmental impact assessment
We offer expert opinion for vibration and ground-borne noise problems as well as climatology, light/shades and seimicity for infrastructure projects like:
- Railway tracks
- Road constructions
- Railway stations
- Airports
- Pipelines
- Shopping malls
- and others....
Blasting engineering
- Low-vibration blasting
- Evaluation of limit values even in sensitive areas (e.g. springs)
- Appointment of blast-induced dynamic stress
- Assessment of vibration induced damages
- Blast experience with explosives up to 4000 kg
- Vibration measurement and monitoring
Engine vibrations
Analysis of the emission of technical machines as well as vibration protection consulting for high-precision machines (electron microscopes, NMR-facilities) or computer hardware (server, storage systems,...)
Vibration protection
In addition to analyses, we offer vibration-related consultancy.
Seismicity
We offer expert opinions for the assessment of potential hazards of earthquakes to sensitive infrastuctural facilities.
Climatology
Expert opinion for environmental impact assessment.
Light/Shades
Expert opinion for environmental impact assessment.
Concentrations
Concentrations studies for environmental impact studies.
Radioactivity measurements
We determine the activity concentration of natural as well as artificial radionuclides in environmental samples of all kind. We assess and survey materials (e.g. foodstuff, construction materials etc.) as well as projects with respect to medical and environmental aspects of radioactivity and ionizing radiation. We also conduct dose rate measurements for gamma and neutron radiation. We investigate and certify the lawfulness of the official limits.
Irradiation
We irradiate technical materials with neutron as well as gamma radiation. Contact us for details.
Neutron Activation Analysis
We are specialists in Neutron Activation Analysis (NAA). This is an analytical method dedicated to the determination of (trace) elements in samples of all kinds. For certain elements, it is the most reliable analytical method, furthermore it is highly reproducible and has excellent detection limits. A huge advantage is that NAA can be conducted without any major sample preparation steps. Further it is bulk sensitive and not only surface sensitive (as many other analytical techniques are). Thus NAA is the method of choice for analytical challenges especially in complex sample matrices. Contact us for details.
