Afin de réduire à un échelle plus commode la très vaste gamme de pressions acoustiques, on utilise l'échelle des décibels (dB). Les niveaux de pression acoustique exprimés en dB traduisent plus facilement les impressions de l'oreille humaine. Une modification du niveau de 10 dB correspond approximativement à doubler l'intensité perçue [...]. Sur l'échelle des décibels, un chuchotement à 2 m de distance aurait un niveau sonore d'environ 35 dB(A) alors que le niveau sonore moyen des bruits de fond dans un bureau serait d'environ 40 dB(A). Un marteau-perforateur à 15 m de distance peut engendrer un niveau sonore de 95 dB(A), alors que dans une discothèque les niveaux de bruit peuvent atteindre 110 dB(A).  2, fiche 8, Français, - %C3%A9chelle%20des%20d%C3%A9cibels

... RACE, an innovative, chic, and highly flexible method of organizing individual work areas [designed by Montréal designer David Ball]. RACE consists of components that are designed to be easily adjustable. Space dividers, desktops and filing space are all supported by a horizontal beam with a so-called raceway, a hollow core containing electrical wiring and data communications cables. The beam rests on metal posts at desk-top level, providing easy access to electrical outlets and allowing air to flow freely around and under the work area. Padded acoustic panels can be snapped onto vertical bars that rise above the desktop, providing privacy. Unlike similar systems, each piece can be moved separately and the raceway, for which the design is named, is flexible enough to accommodate rapidly changing communications systems. First developed in 1978, RACE has been fine-tuned over the years.... Its manufacturer and distributor, Haworth Inc. of Holland, Mich., acquired the manufacturing rights to RACE in 1990....  2, fiche 10, Anglais, - Race%20system

The system-level structural qualification was therefore limited to a modal survey test to validate the ERA [European Robotic Arm] Finite Element Model, followed by a boosted modal survey test. This test programme is designed to qualify the ERA subsystem interfaces and the ERA and Russian launcher interface points that had not previously been subjected to qualification load levels in lower level test programmes. During the boosted modal survey test, ERA was mounted on a special vibration adapter in the Large European Acoustic Facility, with a set of flight-representative Russian launch fixation brackets(Fig. 6). ERA's natural frequencies were excited by mini-shakers at several load points. The strains were closely monitored to prevent overloading the flight hardware.  2, fiche 12, Anglais, - boosted%20modal%20survey%20test

The present work aims at trying out Acoustic Impact Technique as a possible means of deployment at field level for the purpose of flaw detection in composite helicopter blades. The principle underlying Acoustic Impact Testing is simple. The sound produced when a structure is tapped is mainly at the frequencies of major structural modes of vibration, which are structural properties. Any difference in the sound is necessarily due to modification affected to the force input by the defect in the structure. A study of the force time history of response or its fast fourier transform makes it possible to locate and detect sub surface flaws.  3, fiche 16, Anglais, - acoustic%20impact%20technique
