They are actually always occurring (if the notes as sufficiently dissonant) - so the calculations are nothing more than subtraction ie. 440 - 215 = 5hz
some combination tones are louder than others usually as there is less phase cancellations occurring.
- jacquesm 4y ago440 - 215 = 5? I think you got the principle right but used the wrong A for your example (you used A4, probably meant to use A3)? 440 and 215 would interact as 440 and 430 (an octave above the 215) so you'd get a difference of 10 Hz, not 5. (And the sums as well, of course.)
- an_aparallel 4y agoi did something wrong...and i didnt even get my equals sign right :) Thanks for the correction!
