Aircraft noise reduction is actually a pretty big area of research by aviation companies due to noise regulations. Aircraft noise levels limit things like aircraft traffic, takeoff weight, airport zoning etc, so finding ways to reduce it means more money in their pockets.

Theyre looking for ways to reduce noise without losing money otherwise tho. Hydrogen powered planes have now room for passengers so it probably wouldn’t work. Hydrogen is also very hard to keep from leaking. Ever hear about how much methane leaks from our natural gas lines? Hydrogen does that but much worse. And its much more flammable
