• There are two types of combination tones : "'sum tones "'whose frequencies are found by adding the frequencies of the real tones and "'difference tones "'whose frequencies are the difference between the frequencies of the real tones . " Combination tones are heard when two pure tones ( i . e ., tones produced by simple harmonic sound waves having no overtones ), differing in frequency by about 50 cycles per second or more, sound together at sufficient intensity ."
