What is a palindrome that synonym of sudden noise?

This is a bit tricky! There isn't a common synonym for "sudden noise" that is also a palindrome.

Here's why:

* Palindromes are words or phrases that read the same backward as forward (like "racecar" or "level").

* Sudden noise usually implies something unexpected and loud.

Let's get creative:

* Bang is a palindrome, but it's more specific to a loud, explosive sound.

* Pop could work, but it's not as strong a synonym for "sudden noise."

To make it a true palindrome, you could create a made-up word:

* "Abba" could be a fictional word for a sudden, loud noise.
