Yes totally. My early teen has it, it's worst when they're tired. Just normal everyday noise (in school, talking and shuffling, not necessarily 'loud' stuff like shouting) can make them break down and cry uncontrollably. Needs to leave the class to recover, it can take hours. They were not happy when their sibling had a persistent cough.... Ear defenders and noise controlling headphones help in 'crowd' situations such as museums or airports.
