Cabin noise is a strange thing to quantify. I find it makes a huge difference where you sit. In some seats on certain aircraft, there is a horrible hissing coming from A/C ducting through the wall. Then, there's sitting in front of or behind the engines. I've sat at the back of the A330, and it was loud! Other A330 flights, I've been ahead of the wing, and it seemed quite peaceful. Similarly, I've sat both up front and in the back of the Q400 as well as the non-Q DHC8A, B, and C. The older ones without the noise suppression are overall louder, but in both instances, sitting at the back is much quieter.
As to noisy, I remember the 732 as being quite loud. These days, the loudest thing I sometimes find myself on is the B1900D. But, what a little rocket that thing is! I just put in my earplugs, and enjoy that takeoff.
BTW, if you think noise-cancelling headphones are just not worth it to you, I highly recommend some cheap-ish musician earplugs. Etymotic makes some nice ones like the ER20XS. They reduce the overall noise level, but only -20 db. They also reduce sound fairly evenly across the frequency spectrum. Unlike regular earplugs, you still get some high frequencies, so speech is still quite intelligible.
