  • RelatedゲインNeutralLoanword for gain — the ratio of output to input in electronics; it can also mean profit. A technical engineering term, unlike the broader 「増幅」.
  • Antonym減衰げんすいNeutralAntonym: gradual weakening or fading away, of signals or levels. It is the direct opposite of 「増幅」, which builds a signal or feeling up.
  • Antonym縮小しゅくしょうNeutralAntonym: making something smaller or cutting it back, in size or scale. It opposes the enlarging sense of 「増幅」.

Use 「増幅」 for amplifying signals or intensifying feelings like anxiety or anger, as in 「不安が増幅する」 or 「増幅器」. Say emotions rise with 「高まる」; electronics gain is 「ゲイン」. The opposites are 「減衰」 (fading) and 「縮小」 (shrinking).
