Answer:
21 Hz, 43 Hz and 22 Hz
Explanation:
The computation of the beat frequencies that are generated by this discordant combination is as follows:
As we know that
beat frequencies = |f_1 - f_2|
So
For the first one
= |349 Hz - 370 Hz|
= 21 Hz
For the second one
= |349 Hz - 392 Hz|
= 43 Hz
And, for the third one
= |370 Hz - 392 Hz|
= 22 Hz
