Did you just install a system update, such as 12.3? Sometimes that gets reset when applying a new macOS update or doing an upgrade. In the past, I reverted to Mojave, then went back to a newer version. The "bong" sound was full blast afterward. Usually if there is an issue with your SSD, you'll get a
boot error symbol that provides some general clues, such as a failing boot drive.
This is an older article,
but a good place to start at diagnosing any potential issues based upon startup sounds. If it is just the regular chime, then there probably isn't an issue that you need to worry about. If you have reason to be concerned about it, do a Time Machine backup immediately, and take it to an Apple store or authorized repair shop for diagnostics. However, if it is just the standard chime then I don't see any reason to be concerned, at the moment.
Finally,
go into sound settings and make sure that "Play sound on startup" is unchecked. That's the easiest way to disable the standard boot chime.
