Fascinating clip by Michael Chorost

Michael Chorost is, as some readers may know, a science writer who has a cochlear implant. He published the book that I bought some time ago and he indirectly contributed to me being where I am now, because it was after I read his book that I decided to go for the implant.

Anyway, he has a new film clip about cochlear implants available online here, it's fascinating listening/hearing it. You can actually see his implant (through an Xray) and his processor, as well as listen to a description of what a Cochlear Implant is all about.

Ideal programmes for different listening situations

What is great about Cochlear Implants is that you can choose the programme available based upon the listening situation in hand. A step over nature maybe?

Anyway, this is a list of such situations that I can think of - maybe there's more, if anyone has any queries about suitable programmes just ask!


listening situations:
At the office: Program 1 - or program 3 if it is particularly noisy. I like to get the banter that goes on at an office (a novelty for me) and program 1 (unfiltered) is particularly good for this. When I'm concentrating, however, program 3 (ADRO) is slightly better. Note that distortion is more pronounced with programme 3.
At home: Generally, program 1
Watching TV: Program 3 (ADRO). I like to use an audio cable and for some reason it sounds louder and clearer on program 3.
Music: Program 1/3 - depending on whether it is through speakers or through the cable, in which case, program 3.
Parties: Program 2/3/4: Program 2 if it is a party which is very noisy - for instance, with background music and lots of people talking. Program 3 is best for a dinner party, as program 2 might be too faint for this. In the case of a dinner party on a long table - programme 4 is best, but then again, beyond about 6-7 feet, you've lost everything. This is what I believe is the most difficult listening situation.
Meetings: Program 3/4 - depending on the number of people attending and the distance. Program 4 is better for a smallish meeting around a small table.
Restaurants: Program 4. This eliminates the chatter from people nearby and the clinking of cutlery on plates which i find particularly irritating.
On planes: Program 3 - especially if I'm listening to the In Flight Entertainment or to music. It eliminates the engine noise almost completely - bliss. On the other hand, I like the sound of the reverse thrust on planes, so I turn it to program 1 for landing!
Crying Children: Program 0, i.e. OFF!! Isn't that cool?!?!?!

Different listening situations

Not all listening situations are the same, and cochlear implant users are lucky to have the possibility to adjust what they hear according to the situation in hand.

Firstly, there's generic controls like sensitivity (which is used to adjust what the microphone picks up) and volume (which is, I guess, self explanatory).

Then we have programs that are used to tune to different situations. At a risk of sounding like a sales pitch, one of the reasons why I went for a Cochlear implant as opposed to one from other manufacturers, was the fact that I could actually get 4 programs on my implant. In my speech processor, I have the following:

Program 1: A general program, tuned for my cochlea, as such, but unfiltered.
Advantages: You get everything.
Disadvantages: You get everything.

Program 2: Autosensitivity. The microphone adjusts to the level of volume of where you are and lowers and raises the volume accordingly.
Advantages: Noisy places sound much more manageable.
Disadvantages: In a normal hearing situation, everything sounds very quiet.

Program 3: ADRO: Similar to autosensitivity, but it maintains the level of speech at a normal level.
Advantages: You eliminate your colleagues 'desk noise' as I've come to call it (clicking keys, mouse, telephone ringing etc) while you can continue listening to the radio in peace. Disadvantages: You lose alot of environmental sounds.

Program 4: BEAM: Focuses on sounds that are up to about 4 feet right ahead of you, lowering the volume for others.
Advantages: Good for meetings, restaurants etc.
Disadvantages: Drinks batteries like cola, only picks up a short distance away.

There is also another facility that is called Whisper which is for quiet sounds but frankly, I found this pretty useless, especially in Malta (!)

Unpleasant sounds

I still do hear some unpleasant sounds, but whether it is because they are coming through the implant, or maybe because they are literally unpleasant, is something else. I think it's a mixture of the two really.
In my last flight over, in the inflight entertainment they were showing a film (a Steve Martin film - not my favourite actor!) and I didn't bother plugging in to hear the sound. However, I was surprised to hear the sound of the music in the beginning of the film. How can it be, I wondered, was there some kind of sound 'wi-fi' that my CI was somehow picking up? I then realised that I was hearing the film through the headphones inside the ears of the bloke next to me. All of a sudden I understood why they ask you not to use Ipods, CD Players etc on a train or tube (metro?) in case you get, well, thumped by someone who doesn't like your music, as I was regaled with both the film soundtrack as well as the gentleman's selection of music (which wasn't to my taste, frankly!) for the duration of the flight.
Once in a while - a neighbour in our street starts messing around with his car. He's one of those people who love tinkering with their cars. I've no problem with these people although I can't see what the fun is all about frankly, but what I find maddening is that he continually revs his car engine - aside from the pollution, the noise is SO irritating!
Oh, and crying children as still soooo irritating. Is it the CI, or is it just fact that the sound seems to literally penetrate my bone marrow and give me the shivers?!

Latest trip abroad

Firstly, I would like to apologise for not updating the blog often enough over the past few days. I really have been very busy recently, and this was coupled with a trip I had to the UK over the past few days - life has been hectic.
I will focus on my trip to England, which was my first business trip since the implant. I actually had to condense two business trips into one, as I didn't relish travelling to the UK twice in a week and I had to visit two sites. I instantly noticed an improvement over the last time I travelled 4 weeks ago, as the announcements turned out to be much clearer than the previous time I went. Still relatively unintelligible but I got enough to get along. Anyway, on boarding the plane - another bonus - I could actually understand the captain's commentary (where he stated cruise altitude, ground speed, etc - as an aviation geek this was fascinating to me). I could even understand the (recorded) safety instructions - verbatim. That was really cool.

Upon landing, we departed with a taxi. I could understand the GPS instructions quite clearly (in fact I was quite confused thinking it was the taxi driver speaking to me!) Much hilarity erupted when, enroute, on a motorway, the GPS went barmy and started telling the driver to make a U turn (slightly difficult) or to turn left immediately (which would have driven us off what was signposted as the highest motorway in the UK, wherever that is!). I felt elation that I finally could participate in such humorous events. I checked in, and the lady had a very thick, particular accent that I actually could decipher. Up in the lift. "Lift Going Up. Doors Opening - Third Floor" - lifts seem to speak in capital letters. I spent a very nervous night wondering how I would perform next day. in the meetings. I needn't have bothered - I was understanding everything. Wonderful! The people didn't even notice my implant. I then made a relatively convoluted journey by train to the other customers. I was fascinated to listen to the announcer explaining the different stations coming up. Didn't have to peer frantically out of the window to see if the station we're at was mine. I went to my second hotel, and checked in. I could hear workmen through double glazed windows, working eight floors below and about 30 metres away, changing the floor slabs. Every day, I spoke to Mandy on the phone- even my dad called, which was quite funny actually, as Rina pretended to be the reception telling me I had a call, there I was saying "this voice is familiar" and then my dad coming on and everything sinking in.

Then, on Wednesday - fantastic, I can honestly say that this was the best day I've had, hearing wise, since I had my implant. I spent over 5 hours straight talking to clients, explaining the design of the system we'd made for them. I was totally immersed in the conversation, I was being peppered with (very technical) questions left and right. No problem. I came out elated. I had really done it. Normally something like that would have left me stressed as hell and exhausted beyond all measure, but I was just tired. Fantastic!
The ride down to London was a long one, but it was fantastic being able to talk to my colleague, even in pitch dark, and understand everything. I got on the tube on the Piccadilly Line in the North East (elated to be back in London which is my spiritual home, I would say) extreme end, and had to literally cross London. I was fascinated listening in to conversations people were having (I know it's wrong but couldn't help it!) the tick-tick-tick-tick of the wheels on the track was familiar and comforting if anything.. the whooshing of the wind when we entered a tunnel was not - this was new to me. The warning bleeps of the doors was also new. "This train is the Piccadilly Line Train to Northfields. Next Station is Leicester Square. Please mind the gap". Actually hearing the recorded announcer speaking out the stations with names that are like long lost friends for me (hadn't been to London for two years) was almost comforting. Finally, I got to my destination, London Heathrow Terminal 4. I got into a cab, gave the cabby my address. I actually found a cab driver who didn't know a particular street in London (this is amazing for anyone who knows taxi drivers in London with their prodigious memory for addresses). He repeatedly asked me for tips - address, hotel name, postcode, street name, as he couldn't figure out where he had to go. Remember, he's looking ahead, it's dark, in a taxi. I was understanding every word. Had a chat with him even - fantastic, I never had a chat with a taxi driver before.
Next day - similar, my driver asked me where I was going - I told him back home to Malta. he said he'd never been but had been to Cyprus a few years back. We chatted about the low-cost fares, we agreed that you pay the fare for low cost in other ways like through transport or hotels. Gave him a tip. Got told "thanks, guv" and was aware of it for the first time. Fun!
Immersed in the sea of humanity at Heathrow, I had a chat with the checkin clerk (normally I would just sit there and stare) I bought Mandy some perfume and shook off the rather insistent sales lady (who was Polish I think, based upon my newly developed skill of accent determination!) who wanted to sell me something else. I then bought her some eye cream (why is it called eye cream when you put it on your cheek bones) and the Spanish (or Spanish language speaking at least) lady gave me instructions to tell Mandy not to put it on eyelids but on the top of the cheekbones as "eyelid skin is 50% thinner than the cheeks and you get puffy eyes".
All in all,a total success. How the hell did I manage to stumble along before?!

Red Letter Day

Yesterday was, for me, a red letter day. I received a mail from a colleague overseas asking for a phone conference. With some trepidation, and relatively sweaty palms and forehead. I accepted. I asked a team mate to join me in the room in case, and I picked the phone and dialed, over the Internet. And... it went swimmingly! I had to concentrate, I had to ask for a repetition a couple of times, but all in all, I managed. Very pleased with myself!

Why is this a milestone? Firstly, it's the first time I made a business phone call in my life. This opens up the avenues for me, professionally. And secondly, well, it was the first time I called someone who isn't a family member or a close friend. Quite a progression to change habits of 2/3 of my life where I had to get other people to make a phone call for me.
