밤에는 means at night or as for nighttime.

It is made from:

• 밤 = night
• 에 = a time/location particle, here meaning at
• 는 = topic particle

So:

• 밤에 = at night
• 밤에는 = at night / as for nighttime / during the night, specifically

Adding 는 gives a slight contrast or emphasis. It can imply something like:

• At night, the construction noise is bad...
• When it comes to nighttime, the noise is bad...

This often suggests a contrast with other times, even if it is not stated directly.

공사 소음 means construction noise.

Breakdown:

• 공사 = construction work
• 소음 = noise, unwanted noise

Together, they form a noun phrase: construction noise.

This is a common Korean way of combining nouns, similar to how English says traffic noise, street noise, or machine noise.

이/가 marks the subject of the clause.

In 공사 소음이 심해서:

• 공사 소음이 = the construction noise
• 심해서 = is severe/bad, so...

So the phrase means:

• because the construction noise is severe
• since the construction noise is bad

The adjective 심하다 describes 소음, so 소음이 is the natural subject.

심해서 comes from the adjective 심하다, which means:

• severe
• serious
• intense
• bad

Here is the formation:

• dictionary form: 심하다
• stem: 심하-
• -아서/어서 form: 심해서

In this sentence, -해서 gives a cause or reason:

• 심해서 = because it is severe / so it is bad that...

So 공사 소음이 심해서 means:

• because the construction noise is so bad
• the construction noise is severe, so...

This is a very common Korean expression.

잠이 오다 literally means sleep comes.
So:

• 잠이 와요 = I feel sleepy / sleep comes
• 잠이 안 와요 = sleep doesn’t come / I can’t fall asleep

This sounds natural in Korean, even though English usually says:

• I can’t sleep
• I can’t fall asleep

So the sentence is not literally focused on the action of sleeping, but on the state of sleep not coming.

Because 오다 is being used here, and with 잠이 오다, 잠 functions as the subject, not the object.

So:

• 잠이 오다 = sleep comes
• 잠이 안 오다 = sleep does not come

That is why 이/가 is used.

If you used a verb like 자다 (to sleep), then the structure would be different. For example:

• 잠을 자다 = to sleep

But this sentence uses the idiomatic expression 잠이 안 와요, so 잠이 is correct.

Both can be translated as I can’t sleep, but they are not exactly the same.

잠이 안 와요

• literally: sleep doesn’t come
• means: I can’t fall asleep / I’m unable to get sleepy
• often focuses on difficulty drifting off to sleep

못 자요

• literally: can’t sleep
• means: I am unable to sleep
• can be broader: maybe because of noise, pain, stress, or lack of time

In this sentence, 잠이 안 와요 feels very natural because loud construction noise is preventing sleep from coming.

안 is a common way to negate verbs and adjectives in Korean.

In this sentence:

• 와요 = comes
• 안 와요 = does not come

So:

• 잠이 와요 = sleep comes / I feel sleepy
• 잠이 안 와요 = sleep doesn’t come / I can’t sleep

It is similar to saying not in English, but it is placed before the verb.

Not always, but very often it does.

The ending -아/어서 can connect two clauses in ways like:

• because
• so
• and then (depending on context)

In this sentence, it clearly gives a reason:

• 공사 소음이 심해서 잠이 안 와요
• Because the construction noise is bad, I can’t sleep

So here, translating it as because or so works well.

Yes. 와요 is the polite informal style, often called the 요-form.

The base verb is 오다 (to come), and here it becomes:

• 와요 = comes
• 안 와요 = doesn’t come

This style is polite and very commonly used in everyday conversation.

Less polite/plain forms would be:

• 잠이 안 와
• 잠이 안 온다

More formal style:

• 잠이 안 옵니다

Yes. The Korean sentence has a slightly natural, everyday feel that is a bit more literal than English.

A very literal breakdown is:

• At night, the construction noise is severe, so sleep doesn’t come.

Natural English would usually be:

• The construction noise is so bad at night that I can’t sleep.
• At night, the construction noise is so bad that I can’t fall asleep.

The Korean version sounds quite normal and conversational, especially because of:

• 밤에는 for topical contrast
• 심해서 for cause
• 잠이 안 와요 as a common expression for not being able to sleep

Yes, it can.

Because of 밤에는, the sentence may suggest a contrast such as:

• At night, the construction noise is bad...
• maybe during the day it is less of a problem, or maybe the speaker notices it more at night

The sentence does not explicitly say what happens in the daytime, but 는 often creates that kind of contrast or topic emphasis.

So a learner should notice that 밤에 and 밤에는 are similar, but 밤에는 feels more like:

• as for at night
• at least at night
• when it’s nighttime
