For example, if the fundamental frequency is 600 Hz, the octave harmonic of this is 12, 000 Hertz (or 12 kHz) Harmonic frequencies are always louder than the fundamental. They found that 14 percent of the children had some degree of high frequency hearing loss. Sound waves can behave irregularly, but lets stick to the basics.
