My hearing aid journey, part 2

I now have (and am wearing) my hearing aids. I got them yesterday, and so far my experience is definitely positive.

My initial thoughts were “how loud my clothes are swishing, and how loud this traffic is”, and I really noticed a difference in how my own voice sounded. But I could make speech out better, I think. Going for dinner in a reasonably loud restaurant today was good, and I could make out what my wife was saying easily – and I could listen to the conversation at nearby tables as well.

The effect on musical sounds its a little strange. For some time now, I had thought the top octave of my piano (which is nearly new) was a bit dead, but with the aids in it sounded much better. Indeed, the (real) piano sounded altogether better, with a very strong presence. Oddly, the electric one sounded just the same, which does seem strange. The aids do appear to introduce an artefact: even a pure tone at 2kHz sounds amplitude modulated at about 8Hz, and the exact sound changes depending on the angle of my head. (But a 1 kHz tone sounds much as it did).

I also noticed that listening to a weir on the local river, the sound of it – both the quality and the level – depended on the direction my head was pointing in.

But so far, I think they do make a difference, and my wife thinks so too. I need to test them in a more difficult environment, like a committee meeting or a relatively noisy public location…watch this space.

(A little later on) Playing my clarinet with the hearing aids in was a strange experience. Each note – particularly higher notes – seemed to have a bit of amplitude modulation, a little like vibrato, even though I definitely wasn’t putting any in. I had to take the hearing aids off to practice. Oh well: but if that’s the only problem, I’ll cope. I did hear something a little like this on piano – and more so when I tried playing a MIDI keyboard through a saxophone VST plug-in, but it wasn’t as annoying then!
