How many of a note can we hear problem

In summary, the frequency of the highest note on the saxophone is 1,568 Hz. We can hear 12 harmonics of this note. The frequency of the note one octave below it is 784 Hz, and we can hear 24 harmonics of this note. The highest frequency that a human can hear is 20,000 Hz, and we can double 1,568 Hz 12 times without exceeding this limit.

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?

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 ?

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 .
 

Related to How many of a note can we hear problem

1. How many different notes can humans hear?

The average human can hear a range of 20 to 20,000 Hz, which corresponds to a little over 10 octaves. This means that the average person can hear around 120 different notes.

2. Can some people hear more notes than others?

Yes, some individuals may have a wider range of hearing than others. This can be influenced by factors such as age, genetics, and exposure to loud noises.

3. Is there a limit to how many notes we can hear?

Yes, there is a physical limit to how many notes we can hear. The human ear can only detect a certain range of frequencies, so there is a limit to the number of different notes we can perceive.

4. Can we train ourselves to hear more notes?

While we cannot increase the physical range of our hearing, we can train our ears to recognize and distinguish between different notes more accurately. This can be achieved through musical training and practice.

5. Are there any animals that can hear more notes than humans?

Yes, some animals such as bats and dolphins have a wider range of hearing than humans. Bats can hear frequencies up to 120,000 Hz, while dolphins can hear up to 150,000 Hz.
