[Vocabulary] laugh out loud

[dilodi83]

Does "to laugh out loud" mean "to laugh one's head off"?
Are they used in the same type of context?
Thanks so much.

I think the intensity of laughter is higher in "laughing one's head off".)

"Laughing out loud" simply means that you made an audible laughing sound, rather than a quiet chuckle under your breath.
