I'm not sure where you got this absurd notion from, or who told you this. However, putting up with a noisy environment doesn't really have anything to do with a person's "intelligence". Noisy office environments are distracting no matter what your IQ is. Some people are ok with noisy environments. But not because they aren't intelligent. It is most likely because they have just gotten used to it over time, or are very noisy themselves so they fit right in to that type of environmant. Working in a call center, or a Service Help Desk is a good example of this, and I certainly would not refer to those people who work in those environments as "lower intelligence" because they like it or have gotten used to it. 😀
