What does 귀마개를 끼고 mean exactly, and why use 끼다 instead of 쓰다?

귀마개를 끼고 means with earplugs in / wearing earplugs.
Korean often uses 끼다 for things you insert/fit onto your body (earplugs, rings, gloves, contact lenses, etc.). 쓰다 is more for things you put on top of your head/face (hats, helmets, masks, glasses in many contexts). So earplugs naturally go with 끼다.


Is 귀마개를 끼고 잤더니 the same as 귀마개를 끼고 자니까?

Not exactly. Both can translate like When/Because I slept with earplugs…, but the nuance differs:

  • -더니 (as in 잤더니) commonly implies I did A, and then I observed/discovered B afterward, often based on personal experience. It can feel like “I tried it and (turns out)…”.
  • -(으)니까 is a more neutral because/when connector.

So 잤더니 adds a result discovered after doing it feeling.


Why is it 잤더니 and not 자더니?

잤더니 is from 자다 in the past: 자- → 잤-.
The pattern here is V-았/었더니: After I did V / Since I did V, (I noticed) …
자더니 is V-더니 without the past marker and often suggests something like “(I saw that) he/she was sleeping and then…” or a continuing situation leading to another, depending on context. In this sentence, the speaker means I slept (completed action) and then realized…, so 잤더니 fits best.


What does -더니 / -았/었더니 express in general?

It often expresses a cause/background action followed by a newly observed result, with a strong personal-experience flavor.

Common uses:

  • I did X, and then (I found/it turned out) Y.
  • I tried X, and Y happened.

In your sentence: Slept with earplugs → (as a result I noticed) noise was less audible.


What is doing here? Is it “a little” or “less”?

means less (a decrease compared to before).
So 소음이 덜 들리더라 = The noise was less audible / I heard less noise (than usual).
If you want a little, you’d typically use 좀 / 조금. That’s a different idea (small amount), not necessarily “less than before.”


Why is it 소음이 (subject marker) instead of 소음을 (object marker)?

Because 들리다 means to be heard / to be audible (a kind of intransitive/passive-like verb). With 들리다, the thing that is heard usually takes 이/가:

  • 소음이 들리다 = Noise is heard / I can hear noise.

If you use 듣다 (active “to listen/hear”), then the object takes 을/를:

  • 소음을 듣다 = to hear/listen to noise.

What’s the difference between 들리다 and 듣다 in meaning?
  • 듣다: active—I listen / I hear (actively or as an action).
  • 들리다: passive/ability—it is heard / it sounds / I can hear it.

So this sentence uses 들리다 because it’s describing how audible the noise was, not an intentional act of listening.


What does -더라 at the end mean, and why use it?

-더라 marks that the speaker is reporting something they personally experienced/observed (often like “I noticed…” / “Turns out…”).
So 덜 들리더라 feels like: “It was less audible, I realized.”
It’s a common ending when you’re sharing a firsthand observation.


Can I replace 덜 들리더라 with 덜 들렸어? What changes?

Yes, but the tone changes:

  • 덜 들렸어 = simple past statement: I heard it less.
  • 덜 들리더라 = I noticed/observed that it was less audible (more experiential, “reporting what I found”).

Both are natural; -더라 highlights the “finding out/realizing” aspect.


Why is the speaker (like I) not explicitly stated anywhere?

Korean often omits the subject when it’s obvious from context.
Here, 잤더니 and -더라 strongly imply the speaker is talking about their own experience, so 저는/내가 is unnecessary unless you want emphasis or contrast.


Is 귀마개를 끼고 only “while wearing earplugs,” or can it mean “after putting them in”?

In this structure, V-고 typically means and/while: putting them in and (then) sleeping / sleeping with them in.
In real usage, 귀마개를 끼고 잤더니 is understood as I slept with earplugs in (the state during sleeping), not just the moment of inserting them.


Could this sentence mean “Because I slept, the noise was less audible” (like sleep caused it)?

Not really. Contextually, 귀마개를 끼고 is the key cause: wearing earplugs reduced what was heard.
Korean often strings actions like this, and the natural interpretation is: (With earplugs in) I slept → so I noticed noise was less audible.
It’s not claiming that sleeping itself reduced the actual noise—only the perceived audibility.
