OROS at Automotive Techdays: Acoustic comfort optimization based on an innovative TPA method


OROS will present its innovative solution in Advanced Transfer Path Analysis (ATPA) to achieve unparalleled noise reduction results in the passenger compartment: Acoustic comfort optimization based on an innovative TPA method

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:



  1. 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.
  2. 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.
  3. 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.
  4. ATPA can split the global contribution of a panel into air-borne noise and structure-borne noise.
  5. 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.

OROS : des solutions NVH toujours plus innovantes, au service des véhicules classiques et électriques

OROS met à disposition de ses clients du monde automobile plus de 30 ans d’expérience et de savoir-faire en NVH. Rencontre avec Guillaume Cousin, Product Manager au sein d’OROS, qui nous en dit plus.

OROS se positionne comme un acteur reconnu en essais de bruit et vibration (NVH). Pouvez-vous nous en dire plus ? 
OROS est une PME française crée en 1985 qui regroupe plus de 40 collaborateurs. Nos produits sont fabriqués en France et distribués dans le monde entier : 80% de notre chiffre d’affaires est réalisé à l’export. Nous avons des filiales aux États-Unis, en Allemagne et en Chine, ainsi qu’un vaste réseau de distribution à l’international.  Dans les années 90, nous avons été pionniers en lançant les premiers analyseurs FFT portables basés sur laptops. Quinze ans plus tard, nous nous sommes focalisés sur le développement de solutions logicielles applicatives : une interface pensée pour l’application est clé pour permettre à nos clients d’atteindre le niveau d’efficacité qui leur est demandé.

OROS: NVH solutions more and more innovative, dedicated to classic and electric vehicles (EV/HEV)

OROS makes more than 30 years of NVH experience and expertise available to its customers in the automotive industry. An interview with Guillaume Cousin, Product Manager at OROS, who is going to tell us more about this.



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.

Réseau Mesure - OROS remet le prix du concours de Mesures Solutions EXPO 2018

Eric Pessarelli, de la société Cegelec CEM (38 - INOVALLEE - Meylan) a été l'un des nombreux visiteurs du salon Mesures Solutions EXPO 2018, organisé par le Réseau Mesure, à répondre au questionnaire de satisfaction.


Les réponses permettent au Réseau Mesure d'améliorer encore les prochaines éditions.
1.966 participants ont fréquenté les allées du salon les 28 et 29 mars à la Cité des Congrès de Lyon (visiteurs et exposants).
Eric Pessarelli est le gagnant du concours car il s'est approché au plus près de ce résultat, avec un pronostic de 1.867 participants.

Intégrée au Pôle Nucléaire de VINCI Energies (1800 personnes), Cegelec CEM  est une entreprise d’ingénierie de 270 personnes, qui se positionne en concepteur, constructeur et intégrateur de machines spéciales et d’équipements « clés en main » pour le nucléaire et les projets scientifiques.

OROS, fabricant et fournisseur de systèmes de mesure de bruit et vibrations, adhérent du Réseau Mesure également implanté sur le bassin grenoblois et exposant à Mesures Solutions EXPO 2018, a eu le plaisir de lui remettre son prix, une montre Apple Watch.
