Metrological support of acoustic measuring installations mid-frequency devices
Abstract
The article discusses methods for measuring the speed of sound, scattering, attenuation and absorption of sound in liquids, on the basis of which the structural diagrams of modern devices have been developed. In real conditions, acoustic measurement schemes are not ideal and depending on specific structure may give different results. The technical and metrological characteristics of the measuring channels of modern acoustic devices are presented. Recommendations are given for the use of GOST in acoustic measurements and it is stated that the metrological characteristics of newly created measuring instruments operating in in situ conditions are at the level of State primary standards.
