Getting new hearing aids fitted
Several years ago, I got my first NHS hearing aids. After one of them go a fault, I was offered some newer Oticon Spirit 3 hearing aids, with "thin tubes", which were rather nice, in that I no longer had to wear earmolds, making them a LOT more comfortable.
About 3 or 4 years on, I was finding I was, once again, having problems hearing people, so I went back to the audiology dept... where I was told "it's time we retested your hearing". So a couple of weeks later, I went back, had my hearing tested (no change to my hearing loss... about -40 to -50dB at higher frequencies), and discussed what the options were.
I opted to go back to wearing earmolds, and I was offered a pair of new Oticon Spirit Zest aids. These are one of the current NHS "standard" hearing aids, and seem to be getting good reviews from those for whom they are suitable. Gone are different programmes for "omnidirectional" and "unidirectional", there's just the one programme, and the HA works it all out for you.
I have my other 3 programmes set for Loop, Loop with Mic, and Loop (Telephone).
Anyway, what I thought I would do it to explain how they set up digital hearing aids. I'm not talking about when they test your ears (and make you press the button when you hear the beep), but when the program up your aids.
The first thing they do is to fit tubes to the earmolds, and then onto your hearing aids, then plug a thin wire from the PC into the hearing aid, so the PC can "talk to" your HA. Tey don't fit the HAs just yet
They have a special little "test rig" that hooks over your ears. On that are several microphones, 2 that just listen next to your ears and 2 that listen down a tiny tube. The first thing they do is to calibrate this, so the ends of the tubes are clipped adjacent to the other 2 mics, then the computer makes a loudspeaker play a load of "hiss" noises. What this does is calibrates the sound the tubes hear against what the other mics hear.
Next, they slip the tiny tubes (I'm talkin 1 or 2 mm thick) into your ear, and fit your hearing aids, with tubes and earmolds on top of the tube.. The thin tube now hears what your EAR hears, via the heraing aid, and the other microphone hears "the world".
Now, the PC knows what your hearing is like.... after all, that why they made you press the button when you heard the tones. So it does an initial setup of the hearing aid, and makes the loudspeaker make "hissing" noises again. It can now compare "the world" to "what you are hearing"... it SHOULD be the opposite of how bad your hearing is, but due to inexact levels from your hearing aid's microphones and "loudspeaker", it won't be quite right.... but it now knows HOW "not quite right" it is.
The PC makes more adjustments to the programming of your hearing aid, and tests it again, until it's happy it's got it right!
Now, all that there's left to do is to remove the little tubes, take off the "test rig" from your ears, and say goodbye.
That was a couple of weeks ago. My brain is STARTING to understand what the Hearing Aids are doing, so they don't sound QUITE so wierd, but I'm expecting it to take another few weeks before I'm starting to "understand" what they are doing.... (If you've never had HAs before, then you should allow up to 3 moths of CONSTANT HA USE to get used to them!)
