Microtech Gefell/MTG ? The Experts in environmental and automotive Noise Measurements
Corresponding on highest demands the MTG service spectrum also contains application engineering, consultation services and the development as well as the construction of special gadgets, equipment and special test benches in the field of interior and exterior vehicle noise and vibration measurements.
Today, there has been rapidly growing demand for special microphones and test benches for this kind of measurements, especially in the automotive sector.
Exterior and Interior noise measurements are of growing importance, not only in the granting of vehicle-certification by official authorities, but also in the sector of vehicle development and production quality assurance.
MTG offers different Exterior and Interior noise test benches for pass-by PST in accordance with ISO and for simulated pass-by measurements.

Exterior Noise Test Benches
for pass-by PST in accordance with ISO and for simulated pass-by measurements with the weatherproof microphone unit WME 960 H/V or the new WME 980 H/V
Measuring method for noise reduction of motor vehicles
Type-approval procedure by accelerated passing according to current ISO
Internationally standardized Measurement procedure:
Operating conditions of the vehicle: measurement of the A-weighted level progression
Approach at 50 km/h (max. 3/4 nominal speed)
Accelerated passing on the right and left twice each,
Pass-by with maximum acceleration - maximum level gives external noise type test value
Gear selection mechanical transmission: 2nd and 3rd gear, level linearly averaged
Gear selection automatic transmission: i.e. highest position (D) with resulting Switching back
The noise level of a passing vehicle is determined with two special weatherproof measurement microphones at a distance of 7.5 m from the center of the road as a function of the distance travelled. The result is set in relation to the respective test requirements and can be evaluated accordingly.
components and calibrations under uniform conditions and with regard to their effects on the overall vehicle, what reduces costs and time.
Interior Noise Test Benches - Test facility for simulated pass-by measurement / Stationary measurement, engine without driving resistance
Test drives on special test tracks are necessary to investigate the acoustics of the vehicles.
The problem with open-air tests tracks is, that external factors such as different weather conditions, ambient noise and other can falsify the measurement results.
The test series are very complex, time-consuming and therefore cost-intensive. For this reason, many vehicle manufacturers test in soundproof, semi-anechoic chambers isolated from the outside world. This makes it a much more efficient way of testing new or modified
The development, manufacturing and assembly of the measuring systems occurs in close co-operation with renowned manufacturers of measuring systems and our customers.
The MTG-range of supply and service comprises complete project planning, procurement and commissioning of all components, start-up of the systems as well as operator training and after-sales service by experienced MTG-specialists worldwide.
Of the excellent quality and functionality a two-digit number of large internationally recognized customers could convince itself during the last years in Germany and abroad
