Frankly, the question is simplistic.. there are multi-factorial aspects to causation of engine sounds, let alone "noise".
As an example, Bristol sleeve-valve radials were noted to be quieter than rival poppet valve equivalents..
(inspite of running higher comp-ratios), with some "noise" reduction - from more complete combustion,
due to volumetric efficency advantages ( visibly evidenced - by an overt lack of exhaust flames, at night),
plus mechanically, by having far fewer recip' components ( pushrods/rockers/valves) hammering up & down..
This C.I. 2T mill ( Napier Nomad) was also fairly quiet.. but as per current F1 - the exhaust energy was
compounded via turbine, rather than simply/crudely - blasted out of efflux nozzles - for basic thrust..
