How many of a note can we hear problem

[AlaskanPow]

The frequency of the highest note on the saxophone is 1,568 Hz.
1. How many harmonics of that note can we hear?
2. How many harmonics of the note one octave below it can we hear?

The book really gives no examples or information on determining number of harmonics, so an explanation of the problem would be great.

Hello AlaskanPow. Welcome to PF !

What's the highest frequency that a human can hear?

 

[AlaskanPow]

20,000 Hz according to my book. Do we do this then ----> 20000Hz/1568Hz?

No.

How many times can you double 1568Hz without exceeding 20000Hz ?

 

[AlaskanPow]

Well i did the 20000Hz/1568Hz and it gave me the right answer of 12 harmonics. I am not sure why it rounded down like that though.

I had a brain cramp.

Of course 20000Hz/1568Hz is correct.

If you round up, the highest harmonic is grater than 20000Hz .
