This demonstration estimates the level of a difference tone.
The level of a modulating tone is adjusted until beats are just
heard between the difference tone and the modulating tone.
During the first and third intervals tones of frequency F1 and F2 and levels L1 and L2 are presented. During the second interval, the modulating tone of frequency FM and level LM is presented as well.
