I wrote (3/20) that "the hearing aid (HE) equips a microphone which doubles the harsh sound (noises from mic + speaker). I think wearing the hearing aid makes ear symptoms worse."
As I guessed that many people say "they can hear people talk (w/ HE) but they can’t understand the words." READ 1st COMMENTS. **Search google "hearing aid, can hear it but can’t understand." This is because human can’t comprehend AES (artificial electronic sound) and natural sound at same time. Our brain is adopted and can alternate to hear between AES and natural sound very fast (appx. 10 times a second) since we’ve been hearing AES for all our lives (radio, cell phone, car radio, etc.). Hearing AES and natural sound alternatively requires lots of energy and hard work (causes "the listener’s fatigue."). Heck, non-a’philes can’t even do it. Therefore, non-a’philes can’t listen your audio system. To them your system sounds like the left speaker in below video.
This is a new filed that no one said before and I just know what I experienced. AES applies to all HEs. Knowing this info, one can use HE more wisely.
