ノイキャン

• 読み: ノイキャン
• ローマ字: noikyan
• 発音: /no.i.kya.n/

意味

Noise cancelling; a shortening of ノイズキャンセリング, widely considered a must-have feature for modern headphones and earbuds.

ノイキャン is the accepted casual abbreviation for ノイズキャンセリング (noise cancelling). It became a key consumer electronics buzzword in Japan as Sony's WH-1000XM series and Apple's AirPods Pro brought active noise cancellation to the mass market. Japanese commuters and students use the term constantly when comparing earphones, and it frequently appears in product reviews, social media posts, and everyday shopping conversations.

例文

1. このイヤホン、ノイキャンめっちゃ強くてびっくりした。
2. ノイキャンあると電車の中でも集中できるよね。
3. 予算オーバーだけどノイキャンついてるから買っちゃった。

避ける言い方

• 「ノイズキャンセル」と「ノイズキャンセリング」は同じ意味で使われるが、「ノイキャン」の略は「ノイズキャンセリング」から来ている (Both ノイズキャンセル and ノイズキャンセリング are used, but the abbreviation ノイキャン derives from ノイズキャンセリング)

よくある間違い

• Confusing ノイキャン (active noise cancelling) with 遮音 (passive sound isolation) — they are different technologies
• Assuming all expensive earbuds have strong ノイキャン — quality varies significantly by brand and model
