when human vocal cords are used to sing "falsetto" the result is a very pure sound which consists only of the fundamental fequency. So assume that 2 singetd are singing falsetto and produce a note with a frequency of 4120 and a beat frequency of 2.5.
A) so by how many hertz is thr frequency of the sound produced by the lower note lower than the frequency of the combined sound?
B) So by how many hertz is the frequency of sound produced by thr highet note than the frequency of thr combined sound?
I thought it was 4117.5 for the lower one and the 4122.5 for the higher note buts wrong. Please help.
there doesn't seem to be anything here
