Translation guide
The English word "oscillation" refers to regular back-and-forth movement or fluctuation. In Japanese, the translation depends on whether you mean physical swinging, electrical/mechanical vibration, or abstract fluctuation. This guide covers the most common and useful expressions.
Describing a pendulum, swing, or object moving rhythmically from side to side.
General term for oscillation or vibration, used for physical objects moving back and forth.
The oscillation of the pendulum stopped.
Refers to shaking, swaying, or oscillation, often used for earthquakes or unstable objects.
The oscillation from the earthquake continued for a long time.
Technical term for reciprocating motion or oscillation, used in physics or engineering.
This machine uses oscillating motion.
Referring to oscillation in circuits, waves, or mechanical systems.
Specifically means oscillation in electronics, such as an oscillator circuit generating a signal.
This circuit oscillates at a high frequency.
Also used for mechanical vibration or oscillation in engineering contexts.
Loanword from English, used in technical fields like electronics or physics.
We measured the frequency of the oscillation.
Describing abstract oscillation, such as in prices, emotions, or opinions.
Common word for fluctuation or change, used for prices, temperatures, etc.
The oscillation of stock prices is intense.
Literally 'up and down', used to describe oscillation between high and low values.
Nuanced term for fluctuation or wavering, often used in physics or poetic contexts.
振動 (しんどう) is a general term for vibration or oscillation, covering both mechanical and abstract contexts. 発振 (はっしん) is specifically for electronic oscillation, like in an oscillator circuit. Use 発振 when talking about signal generation.
I feel the oscillation.
Design an oscillation circuit.
English 'oscillation' is often used for abstract fluctuation, but directly translating it as 振動 may sound unnatural. Use 変動 (へんどう) for prices, 上下 (じょうげ) for up-and-down movement, or 揺らぎ (ゆらぎ) for subtle wavering.
エンジンの振動を抑える必要がある。
We need to suppress the engine's oscillation.
The temperature oscillates a lot.
I feel an oscillation of the heart.
