Why are harmonics so hard to hear?
It doesn't take into account how even- and lower-order harmonics are harder for humans to hear than their odd- and higher-order counterparts. So music composition also plays a small role. Every component adds some level of distortion, so it's prudent to assess numbers to maintain audio output purity.
What causes harmonic distortion in music?
This happens when unwanted harmonic frequencies—ones not present in the original input signal—are generated and added to the output. For example, a THD of 0.1 percent would mean that 0.1 percent of the output signal is false and contains unwanted distortion. Such gross alteration could lead to an experience where instruments sound unnatural.
