I like the net convention that started a decade or so back that put asterisks around a word to connote action. It's a convention I'd advocate for books, too.
*burp*
The sound of a stick hitting the ground is often spelled as "thud" or "whack."
A bell sound is typically spelled as "ding" or "dong."
The whispering sound is typically spelled as "whisper."
The sound of a licking noise is typically spelled as "lick."
In French, the word "sound" is spelled "son."
After eating food? Perhaps a burp?
You would spell it 'hear' if you are referring to a sound that you listen to.
hummmmmmmmm hmmmmmmmmmm
om
It must be possible for the bee to take in exess air when eating, and would have to get rid of it some how, so I think it must release tiny amounts of air (very rarely). but as bees don't have vocal chords it would not make any sound.
burp because they don't stink
B A N G.
vroom
That is probably the sound of water draining through a clog.
There are many ways to spell the "ooh" sound. You can spell it oh, or uh. This depends on exactly what sound it is making.
Sometimes you can't burp because you never did something to do something to burp. If you would like to burp try drinking coke. Could be any any coke. The normal coca cola, diet coke you name it! If it doesn't work try to ask questions on how to burp in lots of different ways. For example How to burp? Or How can I burp? Or How do you burp?
It would mostly be like krack or Snap
