Thats because of the amount of relative wind going over the windshield and wipers. At higher altitudes you can cruise at .78 (redline Mmo) and only be at 250 kias. Once you get above about 270 KIAS, that bird gets loud inside. And at 18,000 feet, you will be doing 320 KIAS near the Vmo limit, but well below the Mmo limit.
I have those sensitive ear plug headsets. I hate being above 250 KIAS! TOO LOUD!!
