One way of treating the addiction is by addressing the chief cause, I think you are underestimating the power of sounds on one’s psychology, go through the article on the link or do your own personal research. For anyone that can’t control how they perceive sound it can be a big problem for them. Again don’t see this from your lens but from others too.
According to the article, sounds can affect someone that is gambling to risk more money. But I see it as watching a movie or a football match without sound. Or playing normal games like PS 5 at home without sound. That can not be enjoyable if you disable the sound. Just finding way to adapt to the sound is better. As for me, the sound is not affecting me at all and I like it.
