Paukenschlag literally means "kettledrum beat" or "timpani roll". It's a dramatic and impactful word that evokes a sense of suddenness and intensity.
In the context of the song, it's used metaphorically alongside "zweitausend Geigen" (two thousand violins) to describe the overwhelming, almost deafening silence between two people. This powerful imagery of a "kettledrum beat" emphasizes the shocking and profound nature of their unspoken conflict, making the silence feel incredibly loud and significant.
A couple sits at breakfast the morning after a fight, and neither of them says a word. Chima turns that quiet into noise: every small sound in the kitchen grows huge, from "Jeder Biss in deinen Toast" (every bite of your toast) to the dishes he stacks away along with everything left unsaid, "Zu den Tellern in die Spüle" (with the plates in the sink).
The chorus pushes the idea to absurd volume. The silence between them is measured at "Hundertachtzig Dezibel" (one hundred eighty decibels), arriving with a timpani crash and two thousand violins, until the paradox in the title lands plainly: "Die Stille ist so laut" (the silence is so loud). He admits he is being stubborn and pays for it, but talking feels pointless when they only go in circles, and the old scars start itching again.
