Misophonia?
The word misophonia literally translates to "hatred of sound". Hatred of sound is in fact an understand for those who suffer from this disorder. Misophonia sufferers are extremely sensitive to sound, so much so that they have sometimes violent reactions to a certain set of sounds that they call "triggers".
Much like individuals who suffer from PTSD, those who suffer from misophonia have a set of triggers. In the case of those with a sensitivity to sound, these triggers can be things like; people eating food, the crunching of ice or chips in someones mouth, the sound of a certain persons voice, heavy breathing etc.
Misophonia is not be confused with hyperacusis (a disorder that makes people sensitive to all sounds). Misophonia is purely a sensitivity to a set of "trigger" sounds. It may be very possible for a person suffering from this disorder to have extreme difficult speaking with a certain person simply because of the sound of their voice while still being able to converse with others.
Misophonia is very rarely given as a diagnoses and is currently considered a sensory processing disorder much like PTSD. As a matter of fact, misophonia and PTSD are very closely aligned both in symptoms and diagnoses.
Quoting Roxygurl:
Oh god she got mad at anything. We would be sitting on the couch or in the backseat of the van and she would turn around and scream SHUT THE FUCK UP OR ILL MAKE YOU SHUT UP.
She is a horrid bitch and I have nothing to do with her anymore.

Quoting Roxygurl:
My mother does. She used to scream and cuss at my brother and I if we laughed with each other and god forbid we do anything else that made any sound.
Maybe there is a specific sound that makes me want to vomit every time I hear it. The sound of an open car window while driving. >.<
