some beeping app

[Flintstone]

I have some app beeping  every now and then and I would like to know which app it is.

I tried nice catch but that does not have the option to monitor notification beeps (as far as I know) 

is there another way to find the beeping app?

Did you install any third party apps around the time the beeping started, @Flintstone? We'd advise uninstalling your apps starting with the most recently installed. This should help find the culprit.
