This program plays a tone in Hertz and shows the Hertz number of the tone. When you leave to hear the tone you must press [R/S] and the number is the max. Hertz frequency that you can hear.

The theoretical range that can hears the human ear is between 16 and 20.000 hertz

Example: For test your ear:

[XEQ]EAR

Calculator display:

0.0000   (One tone sounds for each number)
30.0000
60.0000
90.0000
   .
   .
   .

When you leave to hear the tone press the PC keyboard [R] and the number is the max. hertz number that you can hear.

I tested my ear with this program and I can hear only tones until 12200 hertz. Perhaps I am beginning to lost my ear capacity.
