Для каждого из   режимов Н1–Н4 нижняя частота интегрирования  fmin составляла соответственно 1, 70, 180 и 300 кГц, верхняя частота была одинаковой для всех режимов –  fmax = 10 МГц. В качестве приемников кавитационного шума использовали пьезоэлектрические волноводные датчики. Регистрировали распределения активности кавитации в неоднородных ультразвуковых полях: в объеме ультразвуковой ванны (f0 = 35 кГц) и в поле погружного излучателя (f0 = 21 кГц). Частотный диапазон интегрирования варьировался за счет изменения нижней границы. Установлено, что изменение диапазона интегрирования в довольно широких пределах не оказывает заметного качественного влияния на результат измерений активности кавитации, происходит лишь кратное изменение показаний. Этот вывод подтвержден благодаря использованию датчиков, различающихся своими спектральными характеристиками.</p></abstract><trans-abstract xml:lang="en"><p>The results of testing the spectral-acoustic cavitometer with measurement modes that differ in the frequency ranges of integration of cavitation noise are presented. For each of the H1–H4 modes, the lower integration frequency  fmin is 1, 70, 180 and 300 kHz, respectively. The upper frequency is the same for all modes and  is   fmax  =  10  MHz. Piezoelectric waveguide sensors were used as a cavitation noise receivers. The distributions of cavitation activity in non-uniform ultrasonic fields were recorded: in the volume of the ultrasonic bath  (f0 = 35 kHz) and in the field of the submersible emitter (f0 = 21 kHz). The frequency range of integration was varied by changing the lower bound. It has been established that a change in the integration range within a fairly wide range does not have a noticeable qualitative effect on the result of measurements of cavitation activity, only a multiple change in the readings occurs. This conclusion was confirmed using sensors that differ in their spectral characteristics.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>ктивность кавитации</kwd><kwd>кавитационный шум</kwd><kwd>ультразвук</kwd><kwd>кавитометр</kwd><kwd>спектрально-акустический метод</kwd></kwd-group><kwd-group xml:lang="en"><kwd>cavitation activity</kwd><kwd>cavitation noise</kwd><kwd>ultrasound</kwd><kwd>cavitometer</kwd><kwd>spectral-acoustic method</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа поддержана Белорусским республиканским фондом фундаментальных исследований, проект № Т23М-026.</funding-statement><funding-statement xml:lang="en">The  work  was  supported  by  the  Belarusian  Republican  Foundation  for  Basic  Research,  project  No T23M-026.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Применение ультразвука высокой интенсивности в промышленности / В.
