Abstract (en)
[origin: JPH02223210A] PURPOSE: To permit a patient to more easily recognize the morpheme structure of vowels and consonants and to improve the perception of sound related to the patient having a hearing handicap by making the peak of a restored signal to be conspicuous in a frequency band affected by faults peculiar to the respective patients. CONSTITUTION: A means 1 receiving the signal of sound and converting it into the electric signal, a means 10 for processing the electric signal and means 14, 19 and 20 for restoring the signal of corrected sound from the processed electric signal are provided. A means 8 for selecting at least one frequency and of the signal is arranged between the means 1 receiving the signal of sound and a means 10 for processing the electric signal corresponding to the means. Thus, the band where the patient is affected by the hearing handicap can be improved.
