Definition
Meaning

Frequency
Very low frequency in general language. Slightly higher frequency in British media/publishing due to a greater focus on naval history.

Learning
Memory Aids
Mnemonic
Think of a MINE that listens with its ACOUSTIC (sound-sensitive) ear underwater. It doesn't need contact, just the noise of a ship.
Conceptual Metaphor
A SENSITIVE ISSUE IS AN ACOUSTIC MINE (It will 'explode' if you make the wrong 'noise' near it).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct calque 'акустическая мина'. While technically correct in a technical text, the standard Russian military term is often more specific, e.g., 'акустическая морская мина'. The metaphorical use does not translate directly.
Common Mistakes
- Confusing it with 'landmine'. / Pronouncing 'acoustic' as /eɪˈkaʊstɪk/ instead of /əˈkuːstɪk/. / Using it as an adjective phrase (e.g., 'acoustic mine technology' is fine, but 'the mine is acoustic' is less idiomatic; 'an acoustic mine' is the standard noun).

Yes, though it's a rare and somewhat literary usage. It describes a topic or situation that is extremely sensitive and likely to cause a strong, explosive reaction if disturbed, similar to how the physical mine reacts to sound.
The trigger mechanism. An acoustic mine is activated by sound waves from a ship. A magnetic mine is activated by detecting changes in the Earth's magnetic field caused by a ship's metal hull.
