Janos from "real world audio" (others are not real?)   is not a doctor although he wants people to think he know something. This leeds to the second problem. He started a youtube chanel as a Audio Guru ans ask people to donate money for him. Anyone know who is he really?

what his family name,is his occupation that he claims -is real?

what is his real expereince in Audio?

Maybe Audiophiles are people that needs Guru?

Nerve cells don't regenerate and once they are gone, they are gone. The ringing you may hear is your brain trying to turn up the sound in the effected side. That is why you should always protect your ears when around loud noises. Anything above 95db can potentially cause hearing loss especially with prolonged exposure. When you are at a stop light and the car next to you is vibrating from the boom boom coming out of their speakers you know there is a future seriously impaired hearing loss person.

Almost certainly permanent....as of now. But who knows what the future will bring? Scientists are doing amazing things with genetics, stem cells, etc and it wouldn't be surprising if they come up with a way to "cure" sensorineural hearing loss in at least some of our lifetimes.
