I think I promised to keep you all posted with what was happening.
At 4 week follow up to explore how I was getting on with the filter I am very pleased to report that I have been using it properly.
As I said to the audiologist it has given me about an extra hour over the course of a day when I can do things. I also seem to be just beginning to learn to distinguish between the source of sounds.
The down side of the brilliant stuff has been massively annoying and making me feel sea sick tinnitus in the other ear which also has hyperaucusis.
A mould has been taken of that ear for another filter to be worn for about an hour before bed to see if it helps my brain balance sound better.
Overall its really good news.
Lovenhugs to all
