Have had noise related hearing loss for many nyears. Unfortunately, this greatly damages hearing over then brange of the human voice.
When retired, the Doc referred me to the NHS Audiology clinic. With 30 mins, after a hearing test, walked out with two aids programmed to my ears.
Three years later, called in for replacement, now digital aids. Two weeks ago, one died. Called in for repair, tested, two new aids in 20 mins.
Wouldn't be without my aids! Only come out at night.
If DH has problems, he should discuss with the Audiologist, so that whatever is troubling him can be corrected.
It could save his life, unless he wants to step into the road without looking or listening
Vanity is incurable though!
