Resonoitumisessa

Resonoitumisessa is a Finnish grammatical form used to express being in a state of resonance. It is the inessive case of the noun resonoituminen, which denotes the process or condition of resonating. In scientific and technical Finnish, resonoitumisessa describes a system, object, or component that is currently experiencing resonance, typically due to an external driving frequency close to its natural frequency.

Etymology and meaning. The word combines resonoida, meaning to resonate, with the nominalizing suffix -ituminen, forming resonoituminen for the process of resonating. The inessive suffix -ssa/-ssä yields resonoitumisessa, meaning “in resonance” or “in the state of resonating.” The term is primarily used in contexts such as physics, acoustics, electronics, and mechanical engineering.

Usage. Resonoitumisessa appears in technical descriptions and analyses. For example: “Kohde on resonoitumisessa, kun ulkoinen taajuus on lähellä sen luonnollista taajuutta.” or “Järjestelmän teho vaihteluun aiheuttaa resonoitumisen, mikä voi kasvattaa amplitudia.” The term emphasizes the current state rather than the process as a general concept, and it is commonly accompanied by references to frequency, amplitude, and quality factor (Q).

Related terms. The standard Finnish term for resonance in many contexts is resonaanssi or resonaatio. Resonoituminen and resonoitumisessa are more explicit in describing the ongoing resonant state. In everyday language, resonoitumisesta is rarely used; in practice, writers often prefer resonaatio or resonaanssi to convey the idea of resonance more succinctly.
