Experiments on perceiving the missing fundamental by using two harmonic components tone

There are some methods on acoustic experiments for perceiving the missing fundamental. Listening to one of two harmonic components from each ear and listening to a complex tone of two harmonic components from each ear are the two examples. The latter method may perceive the combination tones also. Computational experiments of the above‐mentioned two methods were done by using AIM (Auditory Image Model). The effect of the value of the fundamental and the effect of the number of harmonic components on extraction of the missing fundamental information and the information of combination tones were investigated. Finally, the result of the latter method was compared with the result of the former method and the effect of combination tones on extraction of the missing fundamental information was investigated. As a result of investigating many data, the fundamental could be perceived easier in the latter method (tone containing the combination tones) than in the former method. Its mechanism was considered.
