The propagation characteristics of ultrasound in sea water and its ultrasonic reflection loss on the sea bottom or on fish schools must be studied for both the design and the practical operation of echo sounders, fish finders... The propagation attenuation in a direction vertical to the sea surface is the result mainly of spherical divergence, but the attenuation in a horizontal direction is caused partly by absorption as well. This absorption becomes larger at higher frequencies... 2, record 1, English, - propagation%20attenuation

The neutron moisture meter consists of two main components, a probe and a gauge. The probe contains a source of fast neutrons, and the gauge monitors the flux of slow neutrons scattered by the soil.

Les humidimètres neutroniques (ou sondes à neutrons) mesurent l'humidité volumique du sol en utilisant la propriété qu'ont les neutrons rapides à être ralentis préférentiellement par les atomes d'hydrogène, qui dans le sol sont majoritairement inclus dans les molécules d'eau. [...] La mesure consiste donc à compter pendant un temps déterminé (de l'ordre de la minute) le nombre de neutrons lents qui reviennent vers la sonde. Ce nombre est proportionnel à l'humidité volumique su sol. 2, record 4, French, - sonde%20%C3%A0%20neutrons

Scanning Laser Acoustic Microscope. This equipment may be used to provide non-destructive analysis of components in such areas as delamination, cracks, voids, etc. In addition, it can provide information on the attenuation of materials at frequencies of 10, 30, and 100 MHz. The measurement is based on the transmission of acoustic waves through a medium(typically water) while the surface of the component under testing is continuously scanned by a laser. 3, record 6, English, - scanning%20laser%20acoustic%20microscope
