There's 10,000 things that affect perceived noise. Cartridge? Powder? Supressor? Velocit, wind direction, air density, reflective/absorbative surfaces and on and on.
As long as the noise at boundary isn't hazardous (<113 dB I think) then neighbour can go spin.
"Most" of the noise is muzzle blast. So supress everything.
Larger diameter pills will displace more air so have "louder" sound signature than smaller ones.
