The purpose of the research work is to develop new and im-prove existing methods of acoustic control of the properties of textile materials, as well as to automate them as much as possi-ble. Research methods - theory of constant, alternating and impulse currents; theory of differential and integral calculus; spectral analysis; math statistics; theory of measurement results pro-cessing; theory of transmission and reflection of elastic vibra-tions. The list of equipment for research - electro-acoustic emitters MA40S4S; electro-acoustic receivers MA40S4R; operational amplifiers AD620; operational amplifiers AD820; operational amplifiers OPA454; generator SDG1005; oscilloscope SDS1072CML +; MICROCONTROL automation tools Micro-chip. The results of the research and their novelty - the foundations of the theory and the layout of equipment for acoustic control of the surface density of textile materials, based on the measure-ment of the parameters of transmitted and reflected elastic vi-brations, have been developed. The main technical characteristics of the developed equipment are an approximate range of surface density measurement from to ; reduced error in measuring surface density . Information on the implementation of the developed equipment - the introduction of the developed equipment into the educa-tional process is being prepared at the Department of Computer-Integrated Technologies and Measuring Techniques of the Kiev National University of Technology and Design. Research work is related to research work that has number of state registration 0117U000740. Recommendations for further use of research results - recom-mended for use in the textile industry.
