Во эксперимента к датчику шума подключают анализатор спектра частот и лроиавод т многократные съемки спектральйой характеристики при различных внешних услови х: .изменени51х рудного п(1тани , шаро« вой и s.n.Ji в теченив эксперименга , 1укоторый дойжен быть длительным, должна постепенно изнашиватьс  и измер ть с  толщина футеровки. Можно ограничитьс  трем  дискретами по шарам и футеровке. Например, футеровка Нсжа  1Ф| ), изношейна  (Фо ){ сильно изношенна  1Ф.д ).In the experiment, a frequency spectrum analyzer and a multi-spectral spectral characteristic survey under various external conditions are connected to the noise sensor. with thickness of lining. It can be limited to three samples for balls and lining. For example, Nsszh lining 1F |
