From your replies, I understand that I expressed myself poorly or it's Google Translate's fault. In the video, the surrounding noises disappear completely and you can only hear that person speaking, and everything seems fine. My concern was that a person with normal hearing doesn't hear this way—that is, they don't completely separate the dialogue from the noise, but they still hear some of the surrounding noise. I keep the dialogue in the foreground, so what hearing aids do, in my opinion, isn't natural. I hope I explained myself better this time.
