My hearing aid journey continued

March 26, 2020

I’ve now had my hearing aids for a few months, and am getting really used to them. They are really good for speech, particularly in noise, and I really do appreciate the birdsong this Spring. Particularly in these difficult days of self-isolation, the sound of the birdsong round here is reassuring: Covid 19 is a problem for humans, not animals or nature. And they are so small and light, I hardly notice that I’m wearing them.

But back to the hearing aids: I’ve learned to take them off/turn them off before I start to play either the clarinet or the piano. The instruments sound different with them on, and they just don’t sound right! For purely listening to music, the sound isn’t quite right either, with a tremolo added that shouldn’t be there. When the music is really quiet, it’s less annoying, but when it’s louder (when will I hear a full orchestra live again?) it’s not so good, so I sometimes have to turn them off again.

However, for listening to speech in a room with lots of speakers, the aids make a huge difference. I can make out what people are saying much, much more easily, and hat has allowed me to take part in meetings in a way that simply otherwise couldn’t.

Of course, I worry about further deterioration in my hearing (I have expensive and powerful glasses too, multifocals as well), part of the gradual deterioration of senses that’s part of the gradual and natural deterioration of the body inevitable as I get well into my seventh decade. And the enforced walking well into the countryside near here mens yet more birdsong. But there is one downside: when Lussa (the dog) barks, particularly indoors, it’s very loud, very LOUD indeed!

[Deleted: depressing reference to CV19]

Still, given all things, it’s been a definite improvement in quality of life, and I’m very happy I went for these hearing aids.

My hearing aid journey, part 2

November 26, 2019

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!

I am be-grandfather-ed

November 26, 2019

On Thursday November 21st, my daughter’s partner, Katy, had a daughter, Avery Skye. I’m really pleased to say that I am now a grandfather, and look forward to meeting her (they live in the USA, so I can’t just pop over with soup and meet her, unfortunately).

My hearing aid journey: part 1

November 18, 2019

For some time now, I’ve been aware that my hearing was deteriorating. At first, I thought it was wax covering my eardrum, and to some extent it was. Last time (a few years ago) I had my ears micro-vacuumed, it really helped: previously I had gone up to students talking to me in tutorials in order to make out what they were saying. And again when I had my ears micro-vacuumed again recently, it did help, but my wife has been telling me for some time that I wasn’t hearing well.

I did have a simple pure tone audiogram produced a few years, ago, and it did indeed show 40dB or so lost at 4 to 8kHz, but I was not impressed by the audiologist who did the test. But now, having been impressed by the people who did the micro-vacuuming this time (Edinburgh Hearing Practice, at their Auchterarder location), I decided to go for a test with them.

This time the test was in a soundproof booth, and as well as pure tone audiometry, they tested me on isolated words presented to single ears (dichotically), and to speech presented in babble noise. This time I was impressed by the testing, and I could see from the results that my hearing had worsened, and I could see from the errors I’d made in identifying words that my loss of higher frequencies was getting in the way. I’d also noticed that I was finding it harder to make out speech in busy environments, or where there was often more than one speaker – in the common room, or in meetings, for example. It was beginning too make me stop attempting to have conversations in crowded environments

So it came as no surprise to me that my tester reckoned I should get a hearing aid. I know from my professional background that it’s worth getting an aid before one’s hearing really deteriorates too far, so I was open to his suggestions.

I went for it: two behind-the-ear (BTE) aids, with the receiver in the ear-canal (so my residual hearing should be unaffected). I’ll post again once I have them to try!

Arran Gare’s Book “The philosophical foundations of ecological civilization”

November 6, 2019

I’ve had a great deal of respect for Arran Gare for quite some time now, having read some of his philosophy while working on my (and Plamen Simeonov’s) Inbiosa project. Fairly recently, I had read a review of this book, and I thought it would be good to read it. I had to get it on inter-library loan, as my first impression was that it was rather expensive… but now I’ve found there’s a paperback version too, and I’ve just received it.

This is an important book. It styles itself as a “manifesto of the future”, and it is an attempt to push philosophy back into the mainstream of thought, an attempt to move away from the fashionable reductionism that mainstream science takes, and an attempt to make this new world-view able to deal with the real problems that face society. I’m not a professional philosopher (though I did study two years of Natural Philosophy many years ago at Glasgow University), but I have been a professional University scientist, and his critique of the managerial and impact-led modern University struck home.

How can I encourage you to read this book? It gives a philosophical backdrop to the recent upsurge in environmental politics, it provides a philosophical explanation of the commodification of people, of the way in which democracy has been attacked, and liberty and freedom have been turned into purely financial issues. It’s not always an easy read, but it is certainly much more readable than other philosophy books that I have looked at.

Why should you read it?

  • If you are a scientist it helps you to understand the universe as interacting processes, rather than attempting a totally reductionist understanding, which is impossible, because the universe is always interacting and interconnected. (Pure reductionism only works if you can control all the circumstances, like , for example, in the LHC at CERN: but it’s not much use if you want to understand biology or societies or economics).
  • If you are concerned with ecology, it provides a philosophical backdrop to why we have the ecological problems that we do, and perhaps some hope that there might be some ways of going forward to tackle some of the underlying issues that led to the ecological problems, rather than looking for purely technical solutions, that will almost certainly not work.
  • If you are involved in politics, because it might help you to see a different way forward from the purely economic measurements that dominate current politics,. at least in the UK.
  • If you’re an economist, because it might help you to realise that it’s time to re-train (!)
  • … and if you’re simply a living human being, because it will help you to understand how you have been being sent down the garden path by corporations and politicians over the years.

I’ve read about half of it now: the introduction, chapters 1,5, and 6, and the Conclusion. I strongly recommend you read it too!

Fake Blues: gig on Saturday 17th August!

August 10, 2019

Yes, Dave Topliff and I are playing a gig again! Saturday 17th August, 9pm, at the Allanwater Brewhouse in Bridge of Allan. It’s all bluesy jazzy music, Guitar & Vocals (Dave Topliff), and Piano (me). A mix of new songs by Dave, plus covers of some older bluesy songs. And by bluesy we don’t mean just 12 bar blues (though there’ll be a little of that), but good bluesy numbers…

Free entry (and very good beer as well, though it’s not free).

Be there or be square!

The Richard Michael Jazz Summer Course

July 13, 2019

Last week I went to the Richard Michael Jazz Summer Course. It was held in Kilgraston School, which is about 40 minutes from here, but I went as a residential student.

I’d registered piano as my main instrument, with clarinet as a second. But I quickly realised that it was better to have a single instrument, and I decided that I’d concentrate on the clarinet, as I only took it up a bit over two years ago, and really want to get into jazz and klezmer on it.

It was a good decision. The saxophone and clarinet tutor was Gordon McNeil, and I really learned a lot from his classes. I’d never played a jazz solo on clarinet before, and didn’t really understand how to put together a solo in a single note lead instrument. We studied minor pentatonic scales, and how to add to them, we studied chord structure (which I was quite familiar with, but still learned more), and even what a sax or clarinet player carries about for when things go a bit awry with the instrument. And perhaps more importantly, how to structure practise for jazz, something I had been having difficulty with (I understood how to practice classical music and scales, but not what to do to make soloing easier). Gordon is both a brilliant musician and teacher!

The course sets up a number of combos: six in this case. I was in combo five, run by Gordon and Hilary Michael (the surname is not coincidence: she is Richard Michael’s daughter). We played few tunes, including Take Five and Song for my Father on which I played by first clarinet solo, both in practice, and in the final concert. It seemed to go well – it was a very supportive environment.

I also went to the jazz choir run by the amazing Debra Salem. She had us learning and singing in an mixed voice choir, teaching us each part. We had the equally amazing Eliot Murray accompanying us, both in practice and in the final concert.

What can I say? It was a really excellent week, one that far exceeded my expectations. It was full-on and intensive – I played more clarinet and some piano too in the evening jam sessions. I learned a great deal (and I know there’s a great deal more to learn), and met some really good amateur musicians, ad well as the professional tutors.

I hope to come back next year!

St John’s Day, 2019

June 24, 2019

A good day.

Brigitte went to Germany, and her travels all went well.

My day began with seeing Brigitte off, then going out with Lussa. A pleasant walk, not raining, Lussa returning when I threw a ball for her, behaving well – the use of the long lead really makes a difference for me not worrying about getting a puppy to return.

Then home. I’d been thinking for a little while that I’d like to get the Bb real book materials on to iGigbook on the iPad. But beyond loading the .pdf’s into the app (without an index, so I had to look at it in sequence, making me favour jazz pieces which come at the start of the alphabet), I hadn’t properly loaded them. I managed to find out how to do this: it doesn’t work quite correctly, but it’s much better than nothing. I can choose between a C and Bb version: it doesn’t quite work, as it tends to be a page or two out, but that’s (just about) playable with. This felt like a real win, making the iPad much more usable for playing with the clarinet.

Lunch with Eleanor. Good to see her, changing her work patterns in a good way for her, and we had a decent lunch, followed by very good coffee at her’s.

Home again, had another wee walk with Lussa: wandered to the station, decided I’d take a train if there was one there – liked the idea of not being planned, but just reacting to external events. And here was a train, so off to Bridge of Allan, for a coffee at Ciao. Except that Ciao is closed Mondays. But, I had a coffee instead in the Westerton, where they made a suitable fuss over Lussa. Back home again, and thought I’d look at my University Email. Normally , this its very boring, consisting of calls for papers at conferences, jobs being advertised, new journal papers near but not in my research area, and some requests for me to referee papers (which I do quite a lot of sometimes). But this time there was an email telling me that “my new mac mini had arrived”. Now, I currently run an ancient Mac Pro (2 CPU, each 4 core, 20Gb memory etc: 2007 or 2008 vintage), which won’t run the current macOS , and isn’t supported (officially) for Matlab 2019 (but it works). So when a call came round for new equipment t, I responded by requesting a new Mac – and while I’d like a new MacPro, I though that was unlikely. But I’d heard nothing further. So this was a very nice surprise.

But the best of the day was as I was preparing to take Lussa out to her class. I had a quick look at my emails, and here was one from ABRSM about my Grade 5 clarinet exam. Now, I sat it two weeks ago, and I’ve been awaiting the result. I knew I hadn’t played well, I was really nervous, and my hands got really sweaty (which they don ‘t usually)…. whatever. Anyway I’d passed, with 109/150. I was really pleased to read this! But I also really had to go out with Lussa right away…

And then the class with Lussa in Alva went well. Lussa herself seemed more relaxed (she knows all the dogs now). I mean, she didn’t behave wonderfully, and she definitely has ideas of her own, but she was good enough (and I’ll settle for a good enough dog)!

Home now: a phone call to one son who didn’t get caught in the flooding in Edinburgh, and email conversations … bedtime now.

A good day. Perhaps not exactly the weather for St. John’s day (nice enough earlier, then dreich – name recently proposed for the new Scottish currency by one Mr. Watt – and I drove through some torrential downpours and flooding), but still a good day.

two thirds of century…

June 3, 2019

Today I’m 66 and 2/3, two thirds of the way to a century (not that I expect at all to live to 100). May has been a difficult month, with three deaths: my son’s fiancĂ©’s mother and grandmother, and now my mother-in-law. Two of them were over 90 (98 in my mother-in-law’s case) but death is still sad, whatever age it occurs at.

I was thinking back to when I was 33 and third, half the age I am now. That would be Jan 3, 1986.

I was living in Blackford, Perthshire, with why daughter Eleanor, in a rather strange house on Moray Street. I had met Brigitte who would become my wife (but not till 1987), and we were having a romance by letter and the occasional (expensive!) phone call. I was hoping it would go further…

I was a young(ish) lecturer at Stirling University, very excited by being a member of the newly formed Stirling University Vision Group, with Francis Pratt, Bill Phillips, and the late Alistair Watson. Myself (a computer scientist/mathematician), an artist, a psychologist, and a physicist turned environmental scientist. We were an interdisciplinary grouping, trying to understand aspects of perception, particularly visual perception.

By the January, we had read papers by Hopfield on what became known as Hopfield Networks, by Hinton on Boltzmann machines, and (I think) a technical report on Back-propagation. No wonder we were excited!

How much has changed? Lots and little. We knew about encoder networks, and linear and non-linear projections. The machines we had were not powerful, and that limited what we could do. Still…

Teaching was in Pascal (I think…) and I introduced the communications and networks module to Stirling (I’d taught it previously at Glasgow).

People smoked in their offices. Rooms still had some lighting missing, reflecting the closeness to financial disaster that Stirling had come to in the early 1980’s.

All this seems a long time ago (it was a long time ago). I’ve married, brought up two boys, both now independent. And Eleanor has had her own wee flat in Stirling for more than a decade…And I’m now an emeritus Professor.

Pointless exercises

April 24, 2019

I used to think that writing technical articles for academic journals was a “write-only” exercise: but now I realise that this is nothing in comparison to keeping a blog!

At least with the journal papers, I had a reasonable number of citations, but this blog seems to get read by a few of my immediate family, and that’s all. So I think I might leave it there.

The temptation is to write something so outrageous that I would know if anyone had read it. But for now I’ll resist that temptation.

Meanwhile, here’s a picture of our puppy. She’s a 4 month old Airedale Terrier (Airedale Terror?). That seems to be what’s really popular on the internet these days. Dumbing down? Nostalgia for quieter, more peaceful times?
