I am at 13 months with noise induced T and H but my T is on the lower side so I decided to do HBOT. I did my 5th 90 minute session at 2.4 ATA. I plan on doing at least 10 sessions. The are pricey, about $355 per session but this place claims to have helped people with T and sudden hearing loss. I’m really hoping it helps a bit at least. Will keep you guys posted with any progress. So far there has been no change.
