Access To Work or similar funding for dual hearing complexity

I just got an Access To Work fund. I wanted two things but only one was viable. When I spoke to a Neuro psychiatrist I explained that although I have cookie bite hearing loss I also have hyper-acausis and this caused tics and muscle spas spasms. If like to see a neuro-audiologist with a view to getting a hearing aid which can double as a frequency blocker. I just know it will help with being able to cope out of doors and work.  What is the correct route? This would be a private referal because the NHS would have no idea what I was saying so I would need to see someone privately
