Исследовались колебательные процессы в спокойном Солнце вне корональной дыры на разных уровнях солнечной хромосферы. Использованы спектроскопические наблюдения линий ионизованного кальция (K, H и 849.8 нм), полученные на Автоматизированном солнечном телескопе (АСТ) Саянской солнечной обсерватории. Был проведен спектральный анализ временных серий для ряда параметров линий. Выполнено сравнение результатов, полученных в данной работе, с результатами нашего исследования колебательных процессов в спокойных областях, находящихся в основании корональной дыры. Показано, что мощность колебаний выше в области спокойного Солнца вне корональной дыры. При этом имеется общая для исследованных областей тенденция уменьшения мощности колебаний с высотой для всех диапазонов частот, кроме низкочастотного, в большинстве хромосферных структур. В структурах с пониженным магнитным полем наблюдается рост мощности с высотой до высот нижней хромосферы с некоторым уменьшением ее к верхней хромосфере.
