German term or phrase: überkritische Lagerung
Der Zusammenhang zwischen Frequenzverhältnis L = f/fo -(f = Erregerfrequenz, fo = Eigenfrequenz) und Isoliergrad ist der Abb. 5 zu entnehmen. Wie ersichtlich, tritt erst ab einem Abstimmungsverhältnis f/fo > 2 eine Isolierwirkung ein. Man spricht in diesem Fall von einer „überkritischen“ Lagerung.

Bei „unterkritischer“ Lagerung - f/fo < 2 ist für die Grundschwingung - Drehzahl der Maschine - keine Isolierwirkung zu erwarten.

The text is about vibration isolation panels.

I'm struggling to find many references to this in German or English outside of this one particular text. I thought maybe "resonance" for Lagerung, e.g. subcritical or supercritical resonance. Would that work?

supercritical mounting


Explanation:
"Lagerung" refers to the support of the item or machine being isolated. Could also use "suspension" but "mounting" is typical for mechanical engineering systems, such as rotating machinery.

Um Schwingungsisolierung zu erreichen, muss die elastisch gelagerte Maschine über ihrer Eigenfrequenz, also im überkritischen Bereich, betrieben werden.

This supercritical mounting causes the best isolating degree regardingmechanical and acousticvibration exciter (picture 11.5b).

supercritical storage


Explanation:
occurs only from a tuning ratio f / fo> 2 an insulating effect. In this case one speaks of a "supercritical" storage.
