I've just come back from having my hearing tested by the NHS for the first time in about 6 years. The graph of my hearing looked a bit like a capital 'Z' which has been somewhat straightened out. First 3 points, lower frequencies, were said to be about normal, 10 to 20db down, and the last 3 upper frequency points were 70 to 75db down (at 8,000KHz IIRC), with the points in between forming a straight line between the two, so quite a loss at the top end. The hearing aids themselves have also changed in the meantime, getting smaller but more importantly, increasing the volume more at the upper end. Things in normal life sound so much clearer now as the upper frequency loss is what makes consonants (at the beginning and ends of words) easier to hear so speech is more recognisable. I'm looking forward to listening to my speakers this evening as I expect to notice the benefits. Please bear this in mind when reading any audio reviews or opinions from me in future . Listening to phones it is not really possible to use the hearing aids and I'm not sure that, even if it was, any benefit would be gained so I'm going to ask Frans if he can incorporate the same sort of hearing amplification within my favourite cans . No letters of sympathy please . Dave.

Hi Dave,
Can you PM me the 'plot' of your hearing, would be great if it also had a 'target' what it is supposed to be. Maybe a filter with 'countermeasures' can be made.
corrections bigger than say +20dB cannot/should not be made and completely missing frequencies cannot be 'improved'

Hi Frans, My request for a headphone correction filter was only half serious but it would be marvellous if you could do something to help . The only plot I could give you ATM would be one that I could conjure up from memory. Basically what I was shown on their PC monitor was a chart that seemed to start at zero and end at 8,000 on the horizontal (frequency) axis - on reflection this might have been log scale. The vertical axis, starting at the top at zero and went down to 100 at the bottom, was a linear scale. Again, on reflection, this might have been expressed in percentage or decibels - both my wife and I would guess at decibels (she was present during the testing). Based on this I could draw an approximation of what I recall but I suspect this may not be a lot of use for your purposes. If so I may be able to persuade the audiologist to do me a print of the charts but that may take a while. What I do firmly remember is that both ears were very similarly affected, both charts almost identical and the audiologist also said that the bass end was not too bad, almost normal, but there was "mild to moderate" hearing loss at the top end. PS: I have found an e-mail address for the Audiology Dept. so I will e-mail them a request for a copy of my charts - I'll keep you posted . Meanwhile, many thanks again. Cheers, Dave.

All that added top end might come as a terrible shock, Dave!!!
You weren't that keen on the K550 top end so you are detecting it.

Might it be that what I didn't like about the K550 was the bit of the top end that I wasn't getting, in other words the bit that I was getting seemed incomplete? I must admit these new hearing aids they fitted today (with same ear moulds as before) are certainly an improvement on the previous ones, both in terms of conversations with Sue and listening to the TV. Either the technology has improved or my hearing has significantly deteriorated, or a bit of both . Dave.

Hi,
I am a new member here, this will be my first post. Couldn't help but share a quick story on hearing aids. I have a good friend who was fitted with hearing aids about a week before my wife and I got together with he and his wife for a visit. After lunching, the ladies wanted to visit a local outlet mall. well, for my friend and I shopping in outlets is like a cold shower so we poked around until we found the Bose store.
Needless to say, we entered the store just in time to be hit with some serious acoustics. I noticed my friend aggressively shaking his hand in what I thought was anger. Come to find out, his hearing aids have a remote control and he was furiously turning down the gain.
We both had a good laugh, but I was amazed at the technology improvements that has developed in the acoustic supplement arena.

Hi Duane, welcome to DIYAH. My Dad had a hearing aid for a few years before he died. It was just for one ear but he just wouldn't wear it!! So, knowing he was deaf on one side allowed us all to be really rude about him on that side and polite on the other!! That was until he caught me out when he had it in. They are SO small, that you often can't easily see them. Beware of deaf people!!!!
