In article “Doppler Effect and neutrino acoustic signatures”, published in the journal “LA MULTIAPP” on February 25, 2022, I was forced to touch on an astrophysical topic when, in the data stream obtained by monitoring the acoustic noise of the earth’s crust with high amplitude resolution (more 240 dB) and in a wide frequency band (from 0.1 Hz to 50 kHz) events began to appear, the forms and frequencies of which are not typical for geophysics and seismology. Similar forms can be seen in works on the detection of acoustic traces of neutrino decay in water and ice. The possibilities of increasing the sensitivity in measurements in a solid medium are discussed. In addition, underwater and underground facilities are being built that use the effect of Cherenkov radiation. All of these methods require complex and very expensive installations on a huge scale. Even acoustic measurements in water and in wells are very laborious and expensive, and most importantly: such measurements are forever tied to a specific place. Therefore, the creation of a light, compact and mobile device for recording acoustic traces of neutrino decay is an urgent task, the solution of which will allow recording traces of neutrino decay not only in water and the earth's crust, but also in air, into space, on planets and satellites.

Askold Sergeevich Belyakov, a leading researcher at the Institute of Physics of the Earth RAS, has higher technical (1950-1956), economic (1963-1964) graduate school (1968-1970) and political (1978-1979) education, the degree of Candidate of Technical Sciences (1971) and title of senior researcher (1975). He graduated from secondary school No. 3 in the city of Podolsk in 1950. In 1956 he graduated from the Moscow Power Engineering Institute with a degree in automation of production processes and was qualified as a heat engineer. After graduation, he worked in the field of instrumentation and automation in the mining and metallurgical industries. 1960-1968 headed the automation laboratory at the plant "Zaporozhstal" of the Ukrainian SSR. In 1968 he entered full-time graduate school at the Moscow Institute of Chemical Engineering, which he graduated ahead of schedule in 1970 with the defense of his Ph.D. In 1975 he was approved with the rank of senior researcher. In 1980, he entered the competition for the position of senior researcher at the IPE of the USSR Academy of Sciences, and in 1997 he was approved as a leading researcher. He retired in 2016. The total number of publications is 160. Including 43 copyright certificates for inventions of the USSR and patents of the Russian Federation.
