The device you are descibing is an AM radio! You can hear the difference in two frequncies when you miss tune the station, that whine you hear is the resultant tones. Pipe Organs use this technique for producing bass notes in the 32'-64' range - (8 to 32 hz) this is done by using a pipe of one octave above the desired pitch and a pipe a fifth above it. the blend of the two gives a note one octave lower.
