Abstract:
1. A method for enhancing the accuracy of sounds heard by a hearing-impaired listener, comprising steps of: inputting a sound to a hearing aid; determining whether the input sound meets a criterion wherein a proportion of a sound energy over 1000 Hz of the input sound to all sound energy of the input sound is greater than 70%; and a proportion of a sound energy under 2000 Hz of the input sound to all sound energy of the input sound is less than 20%; if the input sound meets said criterion, performing steps (A)-(E) as follows: (A) receiving an input sound, wherein the input sound includes a high frequency section and a lower frequency section, wherein the frequency of the high frequency section is between 1000 Hz and 14000 Hz, and the frequency of the lower frequency section is between 0 Hz and 6000 Hz; (B) increasing the energy of the high frequency section to form a high frequency sound processing section; (C) lowering the frequency of the high frequency sound processing section to form a frequency-lowered high frequency sound-amplifying section; (D) combining the lower frequency section with the frequency-lowered high frequency sound-amplifying section to form a modified input sound; and (E) outputting the modified input sound.
