An acoustic survey is a method of gathering information on the abundance of a fish species using echo sounders. Sound is a form of energy which travels farther and faster underwater than in the air. So using the distance a sound travels and the record it makes when it bounces off of something underwater can tell a researcher a good deal about the creatures passing by underwater.  3, fiche 1, Anglais, - hydroacoustic%20survey

In an acoustic survey, a transducer emits a pulse of sound. The transducer can be either fixed or mounted on a moving vessel. The sound moves through the water until it bumps into something, such as a fish, and part of its energy is reflected back to the transducer. Another device, called an echo sounder, amplifies the returned energy and sends it to a recorder where it registers as a mark.  3, fiche 1, Anglais, - hydroacoustic%20survey

Method and device for detecting a leak from a fuel element of an assembly for a nuclear reactor. The detection of the defective fuel assemblies may be effected under water in the pool, by acoustic, ultrasonic or eddy current methods of measurement. It is also possible to use cells called sipping test containers in which the release of radioactive products by the fuel assembly is promoted, these radioactive products being subsequently carried away by the water or a gas into a unit enabling them to be detected.  1, fiche 7, Anglais, - sipping%20test%20container

... 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 8, Anglais, - Race%20system

The exploration of oil and gas involves the evaluation of a variety of types of information... A 3D seismic survey is a method that allows the creation of images of the subsurface geology by inducing an acoustic wave from near the surface of the earth and listening for the echoes from deeper parts of the earth(much like ultra-sound is used to create pictures of unborn babies in their mother's wombs).

Seam Testing Methods... There are number of procedures available which have applicability on different geomembranes... the ultrasonic impedance plane method works on the principle of acoustic impedance. A continuous wave of 160 to 185 kHz is sent through the seamed liner and a characteristic dot pattern is displayed on a CRT screen. Calibration of the dot pattern is required to signify a good seam; otherwise, it is not.
