Hearing aid and hearing aid output voice adjustment method thereof
A hearing aid and a hearing aid output voice adjustment method thereof are disclosed. The hearing aid includes a microphone, a voice output adjustment module, a voice player, and a voice processing module. The microphone is used for receiving an input voice. The voice player is used for outputting an output voice. The voice processing module is used for receiving the input voice and modifying to the output voice, wherein the voice processing module is used for adjusting sound output energies of at least N steps, wherein the sound output energy of the nth step is greater than that of the n−1th step, 2≤n≤N, N≥3. When the voice processing module adjusts the sound output energy of the Nth step, the voice output adjustment module also simultaneously reduces at least a portion of frequencies of the input voice.
1. A hearing aid output voice adjustment method for a hearing aid, wherein the hearing aid comprises a microphone, a voice processing module, a voice output adjustment module and a voice player, the method comprising:
receiving an input voice;
modifying an sound output energy of the input voice, wherein the sound output energy of the nth step is greater than that of the n−1th step, 2≤n≤N, N≥3;
simultaneously reducing at least a portion of frequencies of the input voice to form an output voice, and wherein an extent of reducing at least a portion of frequencies of the input voice when adjusting the sound output energy of the Nth step is greater than an extent of reducing at least a portion of frequencies of the input voice when adjusting the sound output energy of the N−1th step; and
outputting the output voice.
2. The hearing aid output voice adjustment method for a hearing aid as claimed in claim 1 further comprising reducing at least a portion of frequencies of the input voice for m steps, wherein n≥m.
3. The hearing aid output voice adjustment method for a hearing aid as claimed in claim 1 , wherein the step of reducing the at least a portion of frequencies of the input voice comprises reducing high frequency consonants in the input voice.
4. The hearing aid output voice adjustment method for a hearing aid as claimed in claim 3 , wherein vowel frequencies in the input voice will not be adjusted.
5. A hearing aid, comprising:
a microphone receiving an input voice;
a voice output adjustment module;
a voice player for outputting an output voice;
a voice processing module electrically coupled with the microphone, the voice output adjustment module, and the voice player, the voice processing module receiving the input voice and modifying a sound output energy of the input voice to form the output voice, wherein the voice processing module is used for adjusting sound output energies of at least N steps, wherein the sound output energy of the nth step is greater than that of the n−1th step, 2≤n≤N, N≥3;
wherein the hearing aid is characterized in that:
when the voice processing module adjusts the sound output energy of the Nth step, the voice output adjustment module also simultaneously reduces at least a portion of frequencies of the input voice, and wherein an extent of reducing at least a portion of frequencies of the input voice when adjusting the sound output energy of the Nth step is greater than an extent of reducing at least a portion of frequencies of the input voice when adjusting the sound output energy of the N−1th step.
6. The hearing aid as claimed in claim 5 , wherein the voice output adjustment module reduces at least a portion of frequencies of the input voice for m steps, wherein n≥m.
7. The hearing aid as claimed in claim 5 , wherein the at least a portion of frequencies of the input voice reduced by the voice output adjustment module comprises adjusting high frequency consonants in the input voice.
8. The hearing aid as claimed in claim 7 , wherein the voice output adjustment module does not adjust vowel frequencies in the input voice.
