Deaf? Got an emergency? Dial 114

My No 1 excuse of the moment is that as my knowledge of French increases, my hearing deteriorates in inverse proportion.
Anyone who does not have this problem is likely to say, "You're deaf, you old fool. why don't you get yourself a hearing aid?" But in a recent survey, 65% of users said they were dissatisfied with their hearing aids. The remaining 35% said "Quoi?" OK, I made that last bit up. But it does make one reluctant to spend several thousand Euros on something that might not be much help. Would anyone care to share there experience with these things?
