The BAC One-Eleven.
I remember years ago i was flying round as a flight mechanic on an Air Bristol (dry engines with no water inj) machine doing charters for Renault. We landed in Zurich mid-morning and once at the gate were immediately surrounded by yellow vehicles with flashing lights and people wanting to see our noise certificate, C of A etc. I remember myself, the Captain and F/O laughing and saying "Christ, if they think the approach was noisy what are they gonna think when we take-off!"
We lined up and were given T/O clearance when the F/O put his hands on the throttles and stated "Let the show begin".

I know it is not an Airliner but..... the noisiest (and most beautiful) aircraft ever built was the stunning North American XB-70A Valkyrie. Had no less than 6 YJ93-GE-3 afterburning turbojets. 2 were built in the 60s when fuel was cheap and no one complained about noise. Go here for a look see..

Among US-cert airframes I believe it is still the 747-200 (JT9D-3A) at an even 110 db on takeoff. DC8-55 was a full 4.5 db quieter! Also interesting to note that the Sabreliner 60 is one db louder than the LR25 and more than three db higher than the 24D.
All things being equal, of course, which they never are, of course. The DC8 sure seems louder than the 74, and I would have bet that the LR25 made more noise than any Sabre...

I fly the Gulfstream GII which has a couple of those RR Speys bolted on the back; Awesome aircraft.
As I like to say, "If you're going to burn that much fuel you might as well make a lot of noise doing it!"

that would be me in the LR23, well used to be - not flying them anymore, since jan of this year...
On landing, we tried our best not to make too much noise,,, but on take-off.....well the power is there is there to be used....

As a kid in the late 50s, lived under the approach to what was then 28R at LHR, about a mile from the threshold. From our back garden you could count the rivets under the wings of anything landing, and I swear we had main gear tracks on our roof. By far the noisiest - even with only two engines - was the Caravelle. Hateful bl00dy things they were.

The Spey-engined aircraft had a lovely professional crackle, specially at rated thrust and OAT below about -5. (Ah, those Canberra mornings). I believe JT8D aircraft (727,737,DC-9) made more real noise and were certainly audible BVR. I think the certification figures said so.
Most youngsters may have missed the joy of the early, fanless, 707s and DC-8s which left even the low bypass second generation engines in a very murky wake.

Grew up next to LHR in 60s and some familiar candidates here
Caravelle was phenomenally loud for two engines -mind you the Lightening had two Avons as well- but the Caravelle was always noisier than a Coment with four of the same jets
Trident 3 made a cool noise with the boost jet of course and VC10 very very loud
A different type of noise was the approach 'scream' of the fan engined Seven ohs and DC8s. There used to be a Cinema in Hounslow right under the 28R approach and they drowned out the loudest film
As Pax I flew on all of the above except the Caravelle and of course all the Brit contingent were rear engined so fine for the select few on board and too bad for the plebs outside ( very Brit approach)
For interioir noise I would have to go for the behind the wing seats on a non fan 707 or even worse the RR Conway engined DC 8. Even with the extraordinary giant movable 'silencers' that ran on rails behind the engines this was spectacular. I flew on an Alitalia one of these and to this day it sticks in my mind as the loudest plane ever.
Great thread -imagine a 777 with noise scaled up along with the engine size from a sixties jet LOL

I know they're not that noisy compared to some of the examples made in this thread, but I think that the RB211 noise is one of the finest
and most musical of all engines!! FBW
Noisiest still operational has to be the Tu154. Not the more recent Tu154-M which operates into Western Europe but the original Tu154 with different engines, now well beyond western noise regulations. There are still plenty of them around in Russia, even with the major carriers.
The Il62 went through the same mid-life engine change to the Il62-M but I don't believe any of the originals are still going, though I saw one of the last Kras Air ones perform an elegant, smoky departure from St Petersburg just a couple of years ago.

Maybe we should add a 'smokiest' category too. Ill start the bidding with Convair CV 990 Coronado which also made a really cool if not especially loud (perceived) noise PB
