1) no clue
2) no clue either
3) my bet: dash8-400Q
4) all too loud when inside the cabin
5) 757 due to the fact that they can pretty much operate at idle thrust all the way
6) 747-400
7) A340-300x (since it can not be in cat6)

1) Loudest I've flown was a Cessna 182
2) Cessna 310
4) I've only flown on a CRJ
5) 757
6) The most powerful plane I've flown on was the MD-11, but the loudest would probably be the A330 or the 747.
7) no clue

With aircraft noise levels you really can't just guess -- hard dB facts are needed. And some distinction needs to be made between exterior noises footprint/intensity and interior noise levels...
As far as your #6, Boeingflying31, the A330 is definitely not the loudest widebody. I don't know if you've ever flown on one of them, but for their "genre", they're one of the quietest around...

The learjet 23 and 24 and 25 have to be the loudest.
Have you ever marshalled one out.

I'd have to agree with the Lear 23... I've heard it has the same engines as a T-38 fighter?

Can't figure out whether the questioner is asking about cabin noise or noise on the ground.

The older DH or Hawker 125 made more noise taxiing than many planes do taking off. I don't think dB is the entire story. There is dB at a given frequency that makes them offensive to humans.
For light twins, the BE-50 twin bonanza was pretty damn loud.

Assuming we're talking about loudest/quietest based upon being -outside- the aircraft, I'd have to opine the loudest narrowbody is/was the BAC-111. I thought is was louder than the Concorde, but that's just me...

It depends which noise standard you use: community noise three miles from the airport after takeoff ("takeoff "), airport noise 1500 feet from the runway at takeoff ("sideline"), or community noise under the approach path ("approach").
According to the FAA's noise figures, the quietest a/c in each category is:
Narrowbody Airliners:
- Takeoff: McDonnell-Douglas MD-90-30 (77.2 dB)
- Sideline: Boeing 737-500 (88.2 dB)
- Landing: Boeing 717-200 (91.3 dB) *
* if you consider the 717 an RJ, the next narrowbody is the MD-90-30 (91.7 dB)
Widebody Airliners:
- Takeoff: Boeing 767-300ER (81.5 dB)
- Sideline: Airbus A300B1 (90.7 dB)
- Landing: Boeing 767-200 (95.7 dB)

The FAA's Office of Environment and Energy has noise data for all US and foreign certificated aircraft. I looked up jet aircraft, but they also have data for transport and GA prop planes and helicopters:

The loudest sounds I've probably ever heard, aside from close lightning, is:
An AV-8B Harrier hovering
A B-1 Bomber in full afterburner
The Sonic Boom of the Shuttle returning to Cape Kennedy.
I seriously doubt any plane beats a harrier hovering for shear noise levels. The B-1 is close behind. And the double sonic boom of the shuttle is physically audible event.

Not looking at the official numbers, I'd say the MD-80 is the loudest current major airliner flying today in real terms, my ears.
What is it with all the "is there a possibilty airline X will.." threads? The answer it'll is possible.

1: DHC-Beaver
2: Lear 23
3: KA-100 or Metroliner (got to love the Garrett Engines)
4: No clue
5: 707 not reengined
6: 747-200
Love flying in the Beaver, but any single with a big radial in it is fun to fly.

From my experience, the loudest single prop are the Beechcraft Bonanzas. On take-off, On Bonanzas without Q-tip blades, the prop tips become supersonic, and create quite a bit of noise.
For turbo props, the old Lockheed Electra 188's are loud taxiing.
Lear 23's for small jets.
