〜最中に~ saichuu ni
right in the middle of
Use 「〜最中に」 for something that happens while an activity is in progress, often unexpectedly.
How it works

The meeting is still going when the screen suddenly goes blank. At the red event, the meeting has started but has not yet ended.

「最中に」 emphasizes “right in the middle of doing something.” It is often followed by a sudden or unexpected event.

With verbs, use 「ている最中に」, as in 「洗濯している最中に」. This shows that the action is in progress.

With nouns naming activities, use 「の最中に」, as in 「会議の最中に」. Put の between the noun and 最中.

In the example, the strange noise occurs while the laundry is being done. 最中 emphasizes being in the midst of the activity, not necessarily exactly halfway through it.
