Just about every air intake modification available that lets the engine breath easier will also let a lot more intake and turbo noise be heard than the OEM air filter setup. Plus, you may have a non-OEM turbo and some of them just make more noise than others.
Does your truck have a muffler? When I put a 4” exhaust on mine I did away with the muffler and converter. The only thing in my exhaust was a US Gear exhaust brake.

For about two days afterwards, I could still hear turbochargers ringing in my head. I don’t know if that’s due to aftermarket modifications but seriously, ear plugs are a necessity for my 7.3.
For reference, mine is 2000 super duty with banks chip, banks waste gate, 4”exhaust and air raid air filter box housing K&N air filter.

Pretty much any mod to intake/exhaust or turbo will make it louder. Just for giggles, try stuffing a piece of foam over the top of the filter inside the AFE box. And if your truck is straight piped, the most economical bang for the buck to quiet it down is a 30” auger type resonator. Like a FTE or similar.

When I drove my 7.3l truck to customers, they would wait for me on driveway as they could hear me 2 blocks away.
With 6.7l I could listen to opera music while pulling 7500lb on 6% grade.
That thing would pull heavy at 1300 rpm.

The noise is definitely one of the few downfalls of the 7.3. It isn't even really the engine as a whole but rather the injectors that make most of the noise. I ended up going to single shot injectors which are notoriously louder than OEM so I went backwards in the sound department. Your 4" exhaust is probably the largest culprit along with the filter box.
My truck isn't my daily driver (stays indoors except to haul the camper) and the noise actually helps to put the twin babies to sleep so it actually kind of is a plus (though still annoying after a long drive). Long term if we were cross country RVing I would need to make changes. Either figure out a way to make it quieter or heaven forbid purchase a newer truck and keep the old girl stored as a classic.
I have looked into sound dampening and I think there are some things that could be done to make it quieter but it will never be as quiet as a modern diesel. There are hush panels from the Excursion (hard to find now) that can go on the inside and take a few db off. I've considered adding some thicker sound dampening material to the firewall in the engine bay but that would be very difficult without pulling the engine. Another person considered making under engine panels with sound deadening material on it based off their experience of driving in snow and noticing how much more quiet it was but figuring out how to mount it all correctly would be a pain.
I've seen a few Youtube videos of guys taking their interior apart and adding dampening all over it. It seems that most of these guys are not as happy as they thought they would be. I think insulating the cab helps with road noise but when the engine is making the most noise, it doesn't matter if you reduce road noise while the engine is still the loudest part of the equation.

I did that as I had to replace the floor anyways. I lined from under the dash as high as I could get to just under the back window and the inside of the doors with a dynomat like product, then I put a double layer of jute and carpet. made a significant difference. I still felt guilty starting it up in a campground at 7 am when it was time to get back on the road, but at least it was way more quiet than a dodge 12 or 24 valve haha. but like some have said the 6.7 is more quiet than the gas engines.

Btw, the Onan propane generator that many of us have also got quite a bit quieter when I changed the oil to synthetic.

Do I "love" them? Not really, but they are paid for, run great, do what I need them to do and I know them inside and out. If someone wanted to give me a $70,000 truck, I wouldn't turn them down, but I don't covet a new truck enough to pay the $. I'll run the now 22 year old 7.3s until it doesn't make sense.

I think the main noise on diesel is due to injection and spontanic combustion as the result.
On newer diesel the computer makes up to 5 smaller injections per single combustion, what brings the noise level to what gasoline engines have.
Also turbos get better, quieter ducting.

I considered doing this on my F250 6.0, but I had little reserve weight capacity to carry more items on the truck even if I made more volume available.
