Changing the propeller geometry (for quietness, lower RPM etc) usually requires different settings for the ESC's (like the MPP) or a lower Kv motor to turn larger propellers at slower RPM.
Due to the physical constraints of the designs the small propellers on the Air and Spark must spin fast and noisy to give adequate performance.
Bigger, quieter propellers means longer arms, not so portable and then somebody starts a thread - "Can't DJI make this drone a bit smaller" - Lol, can't win them all so make the best of what you got and enjoy it
