Deep in the article it mentions a 15 dB reduction in noise compared to a turboprop at the same thrust.

Unfortunately, though, they don't give hard numbers… If that's 120 dB versus 135 dB it's still too loud for urban environment. But 105 dB versus 120 would make a huge difference and likely be tolerable for a city if it's kept to landing pads on skyscrapers.

Putting landing pads on skyscrapers is mostly a fantasy. There are only a few such pads today. They can't easily be added to existing buildings because the roofs are already used for antennas and climate control machinery. Weight is an issue. And even relatively quiet aircraft are going to annoy tenants on the top floors.

Then let me share another fantasy with you: reading what you wrote, there's no need to land on skyscrapers then, drop a stairwell - similar to some private jets and helicopters.

Huh? You can't just drop a stairwell from an aircraft. Not sure what you're suggesting there.
