What are harmonics?

Ғылым және технология

The 2016 Flame Challenge asked the world's top scientists to answer a deceptively simple question: What is sound? In response, acoustician Whitney Coyle, who is also a trained musician, demonstrated key aspects of sound--timbre, pitch, harmonics--by playing various notes on a flute.

    Each musical instrument is going to sound multiple frequencies at the same time - though one is the most prominent, and the rest are much more quiet. This different collection of sounds explains why a trumpet and violin playing the same note (same frequency) sound different - there is a different mix of frequencies, even if the prominent frequency is the same. Harmonics refers to that collection of multiple frequencies observed - even without a musician changing fingerings, tube length, etc. Each observed pitch is called a harmonic. You can see each of these harmonics as she plays - looking at the highest three or four peaks in the graph. As the flute player added extra energy by blowing harder/faster, she highlighted the higher frequencies of the harmonic series. Note that all of the same collection of frequencies are visible, though one of the frequencies becomes louder. Hope this helps

    Harmonics are integer multiples of a fundamental frequency. Overtones are (usually rational) multiples of a fundamental frequency. Harmonics are overtones, but overtones are not harmonics. This sort of stuff is much better visualized with a spectrogram.

    In the sense that they are both a result of interlacing wave functions, yes. Though in musical instruments it's mostly about standing waves, where you manipulate the length in various ways depending on the instrument, and the harmonics then comes from the various tones which will fit a discreet amout of wavelengths into that particular length. I'm just getting started on electrical engineering, so I might've missed something (most likely, actually), but as far as I know at the moments at least, harmonics in this context is more about waves from different sources interacting. So I'd say they are related, albeit not the exact same. And I'm sure there's someone out there who could easily make a 6 hour lecture on this question alone.
