All audio systems (artificial sound) sound very harsh and bright. We've been hearing these bad sounds for all our lives for generations, last 150 years. Many tortured ears screaming for help as Tinnitus, loss hearing, Vertigo, etc. After many decades of hearing unhealthy harsh sounds, human ears ignore them by shutting off, stay in insensitive mode. Listen/test how harsh your system sounds like. All your systems sound like the left speaker. Artificial sound vs. Natural sound
I've never heard a hearing aid. I guess they are same harsh sound as any artificial sound in above video.Even worse, the hearing aid equips a microphone which doubles the harsh sound (noises from mic + speaker). I think wearing hearing aid makes symptoms worse. I can't imagine the conversation with others in the left speaker sounds in above video.
If you have symptoms of hearing loss, your ears might be in numb (or insensitive) stage due to harsh audio sounds. I think aggressive Tinnitus and mild hearing loss can be cured by hearing more natural sounds. Listen to live talking radio. Talking with people is good. Listen natural sounds only. Don't listen the a'phile audio system which sounds very harsh, loud, and bright. Don't listen recorded music. The more processed sound is the more artificial harsh sound.
I had severe ear problems, but I'm cured by listening the natural sound audio system. Alex/Wavetouch audio
