| Research Abstract |
Howling (acoustic positive feedback) of hearing-aid gives the speech influence that is bad to hear it of especially severed hearing impairment person. Then, we tried a restraint of howling of this hearing aid there. Howling restraint of this new hearing-aid tis an electronics circuit of negative feedback and didital technique. We let tem have playd this hearing-aid and their hearing-aid. And we compared it with a result of both.
The results obtained were as follows ;
1. Aided threshold level fell to 14-16dB.
2. Speech discrimination raised 15-25%.
3. Thy liked new hearing-aid with daily sound.
