FREQUENCIES MEASUREMENTS


My cups/bells collection:


Clic on the bells/cups to  hear them (Works with IE7).
 


 
Location of the .wav files
(clic to download)
Approx. Freqs. (according to Cool Edit 96)
and  should I'm not mistaken. 
Bell N°0
350 Hz
Bell N°1
920 Hz
Bell N°2
5545 Hz
Bell N°3
4660 Hz (updated, 4460 was wrong)
Bell N°4
5360 Hz

NB= All the .wav  files has been 'normalised' by Cool Edit 96.


It is not so easy to measure the frequencies with Cool Edit. You have to select a part of the wave forms.  I selected the first parts of them.  I you do not do this the reading is obviously false.

Examples:

  >>>>>  4658.8 HZ sounds good.

>>>>> 12.7 Hz is too low. Is it not?


I had built a device (now dismantled) with the cups #3 and the cup #4.
I made 3 independant records of each cup.




Here are the results:

You can see that the freqs of the cups/bells are the same,
should these cups were 'alone'/free or coupled/embeded in a "device".

Now, what could be the use of tuning any bl'  "gap"?

I could, of course, be wrong.
