pulsations
Regular rhythmic throbs
Pulsations are rhythmic throbs or beats—the repeated expansion and contraction of something at regular intervals.
The word most often describes heartbeats or the throbbing of blood through vessels: She felt the pulsations in her temples.
It extends to any rhythmic surging: pulsations of light, sound, or energy.
The pulsations of the bass made the floor vibrate.
