OROS markets itself as a highly-reputed player in the field of noise and vibration testing (NVH). Can you tell us a bit more about this?
OROS is a French company created in 1985 that now has more than 40 employees. Our products are manufactured in France and distributed around the globe: 80% of our turnover comes from our export activities. We have subsidiaries in the United States, in Germany and in China, as well as a vast international distribution network. In the 1990s, we pioneered the launch of the first portable FFT analyzers based on laptops. Fifteen years later, we have focused on the development of applicative software solutions: a well-thought-out interface is essential in order for our customers to be able to achieve the level of efficiency that is required of them.
Simultaneously, we have strengthened our international development with a strong presence in China and in Japan where our n°1 customer is established: Toyota. Whilst the automotive industry remains our largest market, our products are also used in rail and aeronautical fields.What are the solutions that you propose for the automotive industry?
There has been strong growth in NVH applications for the automotive industry in recent years. In line with this trend, we have developed an exclusive solution for transfer path analysis that allows the noise and vibration in the passenger compartment to be reduced. In parallel, we have acquired market-tested software solutions for psychoacoustics, sound design and source localization. Our products also have the capacity to measure sound power based on well-known acoustic pressure and intensity methods. In addition, OROS has historically been a leader in the analysis of rotating machines, offering a technology that allows real-time order tracking, which remains precise even at high speeds. In particular, thanks to this technology, we offer specially-designed solutions for balancing of common automotive components (turbo-compressor, crankshaft, etc.) as well as for torsional vibration analysis.
Concerning structural analysis, we offer high-performance methods that allow machining quality to be optimized, by determining the resonance frequencies of cutting tools. Obviously, this is in addition to classic modal analysis on frames and the various components produced by automotive suppliers.
Lastly, we have very recently launched MODS “Mobile DAQ System”. This is an ultraportable DAQ, paired with the NVGo mobile app: it allows very easy acquisition of noise and vibration signals in a vehicle.As part of your innovative approach, you work in close collaboration with your R&D laboratory. What’s the situation exactly?
We have set up an entire process for innovation, design and approval of our products. We are supported by our own laboratory which contains specialized equipment: an anechoic chamber and other classic NVH equipment (rotating machines test benches, microphone antenna, test structures, etc.). This equipment allows us to place ourselves in our customers’ working situations in order to obtain better design and testing of our products.
We also rely on specially selected pilot customers from academic and industrial contexts, who advise us about how best to design, improve and approve our products.What areas are you working on at the moment?
Aware of the exciting prospects for NVH, in particular in the fields of electric and hybrid vehicles (EV/HEV), we are seeking to consolidate our growth in this market. We are specifically focusing on studying the new phenomena that are related to replacement of IC engines by electric motors. Therefore, we are actively working on a specifically-designed and innovative offer to meet the requirements of these new situations.

The project objective is to propose a full Advanced TPA measurement and analysis solution for the Automotive industry. TPA is an experimental based method to quantify sources and their transmission path contributions to a certain position: typically the driver or passenger position. An innovative technique called ATPA is introduced to allow currently unmatched performances:
- ATPA can characterize the response transmission paths, improving the possibilities of other classical TPA methods by allowing the determination of the part of response due to neighboring subsystems.
- ATPA allows to find panel noise contributions even if the panels are coupled, without any dismounting: other already existing TPA techniques working with panel contributions use the hypothesis that panels are not linked together, which is not a good description of the reality.
- ATPA gives detailed information about the noise and vibration paths. Currently, it gives information about 2-step paths, for example: structure linking point N -> panel M -> target’s position. Potentially, the method can give information about any possible path thanks to the direct transmissibility.
- ATPA can split the global contribution of a panel into air-borne noise and structure-borne noise.
- ATPA provides results on a wide frequency range. Current TPA techniques work only for a low-frequency range. The presented technique allows to calculate noise contributions for mid and high frequencies as well as for low frequencies.
Automotive Techdays is aimed at decision-makers in the automotive industry. The major players in the automotive sector in the Auvergne-Rhône-Alpes region will present their innovations with short demonstrations (5-7 minutes).
OROS provides the automotive sector with a wide range of products and services for noise and vibration measurement. The goal for its users is to obtain an efficient evaluation of the vibro-acoustic phenomena by improving the comfort of the vehicles as well as their durability and their performance.
Rosenberg is a German worldwide company manufacturing motors, fans and air handling units for industries and buildings. The department in charge of fans’ development selected OROS noise and vibration testing systems to make sound power, vibration and temperature measurements on fans.
“The noise measuring takes place in an anechoic room with reflecting plane by the enveloping surface method. It is measured with modern OROS measuring systems” said a Rosenberg specialist for noise measurement.
Rosenberg uses a 12-channel OR36 with octave, FFT and Sound Power software modules, plus 2 temperature plug and play signal conditioners (Xpod). OROS GmbH also provided 12 microphones and 1 impact hammer.
