I have the exact same trouble with mouth noises. I couldn't explain the extreme irrational anger I felt when a co-worker was chewing on something while others hardly even noticed. It used to be very unsettling before I came know that it was a known condition with an official name[1]. While knowing that hasn't cured it, if I encounter someone making these noises, to avoid outbursts, I am now quick to put on headphones and play white noise[2] and mentally telling myself that it's me, not them.
