They suffer from getting surprised by things a hearing person would hear coming long before ...
Arguable, some deaf people have enhanced other senses, and I am frequently surprised by things I should have heard...
Or get an extreme example: neighbours are looking strange at them, because they are loud in bed, and do not notice themselves.
Some deaf people can feel when they are making sounds. But either way, any suffering from that is not caused by being born deaf, it is caused by a social stigma about being loud in bed.
A guy shouting at you: "damn idiot, can you not move out of the way, are you deaf??!!"
Not having to hear such a person seems like a benefit to me.
