Let we listen two sounds of slightly different frequencies at the same time.
Then we can hear some periodic variations of volume with a long period.
Please be carefull! Before using headphones, set Volume control on Minimum!
1. Select different amplitude of second sound and hear/see
how beats become more "sharp" or more "soft".
2. Select "Exact formula" for deep understanding; what does mean?
