Concluding sentence
The article in the related link describes how harmonic imaging is used in ultrasound devices. Basically, you transmit at one frequency, but listen for one of the harmonic frequencies (a whole-number multiple of the original frequency: according to the article, usually the 2nd harmonic, which is double the original frequency - so if the original frequency is 20,000 Hz, then you are listening in the 40,000 Hz range)
Harmonic = Armónico
The fundamental = 1st harmonic is not an overtone!Fundamental frequency = 1st harmonic.2nd harmonic = 1st overtone.3rd harmonic = 2nd overtone.4th harmonic = 3rd overtone.5th harmonic = 4th overtone.6th harmonic = 5th overtone.Look at the link: "Calculations of Harmonics from FundamentalFrequency".
a basic harmonic progression (APEX)
The first harmonic is the fundamental. The second harmonic the first overtone. The third harmonic the second overtone. The fourth harmonic the third overtone. Even-numbered harmonics are odd-numbered overtones. Odd-numbered harmonics are even-numbered overtones.
