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.

助听器的啸叫（声学正反馈）对其听觉不好的言语影响尤其对听力受损者。然后，我们试着抑制助听器的嚎叫。这种新型助听器的嚎叫抑制是一种负反馈和数字技术的电子电路。我们让他们玩了这个助听器和他们的助听器。我们将其与两者的结果进行比较。得到的结果如下：1。辅助阈值水平降至14-16dB.2。言语歧视上升了15-25%。你喜欢的新助听器，每天都能听到声音。
