Understanding 感度 (かんど)
感度 refers to the sensitivity or responsiveness of a device or system to stimuli. It is commonly used in technical contexts such as cameras, sensors, and earthquake detection equipment. When someone talks about 感度, they often imply how well something can detect or respond to subtle changes or signals.
Common Contexts and Usage
- In photography, 感度 often relates to ISO sensitivity, affecting how well a camera performs in low light.
- In seismology, 感度 describes how sensitive earthquake sensors are to tremors.
- It can also be used more generally to describe sensitivity in various instruments or even metaphorically.
Collocations and Patterns
- 感度が高い: high sensitivity, used to praise the responsiveness or detection ability.
- 感度を上げる: to increase sensitivity, often by adjusting settings or upgrading equipment.
- 感度が良すぎる: sensitivity is too high, sometimes causing false alarms or errors.
Usage Notes
感度 is a technical term and is mostly used in formal or scientific contexts. It is not commonly used to describe human emotions or feelings; for that, words like 感受性 or 敏感 are more appropriate. Learners should avoid confusing 感度 with 感覚 (sense or sensation), which is broader and more general.
Understanding 感度 helps learners talk about technology and scientific topics more precisely, especially when discussing equipment performance or measurement accuracy.
