I have mentioned many times: ENT doctors are physicians not tinnitus or hyperacusis specialists. They treat underlying medical problems that cause the tinnitus within the ear and auditory system. They do not treat the tinnitus particularly when it is noise induced with or without hyperacusis, because this is not their area of expertise. Those that have tinnitus it's likely to be mild and easily habituated.
The only way to have a true understanding of noise induced tinnitus and hyperacusis is to have experience them and preferably at a time when they were severe, because they cannot be learnt to any significant degree from a book. Some knowledge can be acquired consulting with patients but this will be limited. It is for this reason I don't have time for tinnitus researches who write reams of data and publish articles, on noise induced tinnitus and hyperacusis claiming to have an understanding of these conditions, simply because they are medically qualified, consulted with patients but have no long term experience of these conditions. They base their so called information on science, which in my opinion is total rubbish.
Science has a role to play in understanding and treating tinnitus caused by an underlying medical condition such as Ménière's disease, Otoscelerois, ETD, Hearing loss, Acoustic trauma, etc. I am not saying they are any less severe than noise induced tinnitus but they are different.
The way to treat noise induced tinnitus with or without hyperacusis, is to be referred to Audiology to see either a Hearing Therapist or Audiologist that specialises in these conditions. Often, these health professionals were either born with tinnitus or acquired it at some time in their life. They will have an in-depth understanding of the condition and the way it can affect a person's mental and emotional wellbeing. This can be particularly helpful when counselling, sound therapy, mindfulness, medication are used as a form of treatment for noise induced tinnitus and hyperacusis.
