Spectrometers are actively used in the field of science and technology. Their popularity is due to their high resolution, measurement speed, and ability to analyze complex spectra containing many lines and noise.
One of the most promising instruments for scientific research is the acoustic spectrometer. It has unique capabilities for analyzing ultrasonic signals and vibration, and also provides information about the mechanical and acoustic properties of materials. The spectrometer is widely used in a variety of fields, including medical diagnostics, acoustics and optics research, quality control, and industrial noise analysis. The use of spectrographs opens up new opportunities for the use of acoustic diagnostics and quality control in enterprises, which leads to improved economic performance and increased labor productivity. Acoustic spectrometers are capable of measuring parameters such as signal amplitude, frequency, vibration shape and phase, acoustic radiation spectrum and other characteristics. They are widely used both in laboratory conditions and in the field. In general, acoustic spectrometers consist of an ultrasound generator that generates the measured signals, and a measuring device that records the distorting factors affecting the area under study. These devices can be used to measure acoustic conductivity, absorption, reflection, density and other characteristics of materials. When using acoustic spectrometers, it is important to consider a number of factors that can influence the measurement results. These include measurement conditions, the presence of electromagnetic interference, the properties of the materials being analyzed, and the structure of the sample. To minimize distortions caused by these factors, a series of calibrations and measurement comparisons are usually carried out
