Yes, the cabin noise level is higher than the previous generation and it is a disappointment (one of many) for a car in this class.
It all depends what you’re coming from.
I came from a 2008 Civic Si with a catless header and full cat-back exhaust. The TLX is infinitely quieter than that.
Also, I regularly am listening to either podcasts or music while I’m driving. But if you’re the type of person to drive around without any audio on, then you may notice it.
