I was at the Audiologist on Friday, for a hearing test. My right ear is perfect, but my left ear is shot, with only the bass being heard (standing next to a very loud guitarist for a number of years. My brother stood the other side of him and he is deaf in his right ear!). Came away with a hearing aid, and it is brilliant.
Amazing what I can hear in the car now. Engine and road noise is no louder, but it is all the little things I can better hear now. I will never leave an indicator on by mistake, as the click clacking is extremely audible. I had a shopping bag behind the drivers seat and every corner I heard it crinkling and the shopping moving.
I am sure I will get used to these sounds and begin to filter them out, but I miss the Sound of Silence!
