Voices (and not the kind in your head)


Quote by DeepThunker

When a piano is played, say 440 hertz, the strings around it, as well as the wood box, resonate. That is to say vibrate. The other string's notes will never be as loud as the 440 hertz note you played. This makes sense as you have energy transfer loss. Because the notes are resonating the other notes are in phase with the Original note.
The waves blend together and create a fourier note.
I am familiar with Jean Baptiste Joseph Fourier. He pioneered what is known today as Fourier Analysis, while experimenting with the propagation of heat, along the shores of the Nile, while serving in army of Napoleon.

I've never heard it called a fourier note. I must amend my earlier post, where I said only harmonics are generated. The other frequencies are overtones of the fundamental 440Hz. Overtones are made up of harmonics, which are integral multiples of the fundamental, plus non_integral multiples or inharmonic overtones.They are (as you mentioned) lower in amplitude. If you were to input those frequencies to a spectrum analyzer (which plots freq versus amplitude), you would see a nice graph of that relationship.

I have heard that our brain may believe it is hearing the fundamental, when only overtones are present. I haven't personally tried this but do know other musicians who have confirmed this.

Ok that would make sense. Could it also be how different people interpret the sound of our voices? Is it possible to have the same frequency and voice pitch with someone else? Does it happen in families?
My younger sister and I sound identical. Even my mother can't tell us apart. The first time I noticed it was when my sister left a message on my answering machine and I was confused at first, because I thought it was me. She sounds just like my recorded voice sounds to me.
