Overtones and harmonics - aren't these the same (apart from counting - 1st overtone=2nd harmonic etc)?


Almost, but not quite. The stiffness of the string causes the overtones to depart slightly from the harmonic series. The higher the pitch (overtone number) the sharper it is relative to the harmonic.

With its wide range of pitch, the piano exhibits this "inharmonicity" to the extent that tuners stretch the octaves. This makes the fundamental of a higher pitch match the sharp overtone of a lower pitch.

Don't get upset buddy, not everybody here has a phD in jerking off like you do.
Feel free to do your own little test if you so desire [:)]

You're right though a mic would have been helpful [:D]

great. do it again with a reference mic and an oscilloscope and bring me some real data.

also, quantify in decibels what volume you considered to be the point at which the sound is no longer audible.

usually this is 60dB less than the source.

This is from Wikipedia:

An overtone is any frequency higher than the fundamental frequency of a sound. The fundamental and the overtones together are called partials. Harmonics are partials whose frequencies are whole number multiples of the fundamental (including the fundamental which is 1 times itself.)


So yes, harmonics are overtones, but not all overtones are homonics, only whole number partials (overtones). Or at least that is the way I understand it.

I think Kevin is merely jerking off with a bachelors degree.

If you guys want to read good book about this stuff get a hold of:

http://search.barnesandnoble.com/Lutes-Viols-and-Temperaments/Mark-Lindley/e/9780521288835

It will answer lots of questions for you.

You're welcome. :)

later
