@Mo8409 Did you get rid of nox? What sound therapy you did? I was doing cricket sound and white noise (wearable noise generators) for short time. I am afraid sound made me even worse, not sure.
Word of advice, @aab. don't listen to anyone telling you what to do especially when it comes to noxacusis. You're going to have to experiment with it yourself. Some have reported significant improvement from protecting to the greatest extent. It's all individual. You're the only one that will know what works and what doesn't.
