I must confess some surprise with people saying that they wouldn't want to listen to music while riding (on the road).
Think about it. If you're doing 15mph average or thereabouts, you're mostly going to be hearing wind noise. Well, I do anyway. Most of the time, its reasonable level, the wind noise, but at other times (downhills) you're going so fast its pretty difficult to hear when there is a car near you.
I will say that I am similar to that downhill rider, being profoundly deaf and using a Cochlear Implant on one ear and a hearing aid on the other.
(Actual thing that goes on the side of my head on the outside)
(The thing that goes inside the skin resting against the skull)
(The artist imagination of what it looks like from the side. You can see the Implant on the side of the skull and a long plastic thing going to the cochlea itself, which is shaped like a snail)
The above pictures are for illustration so it may give you some more clarity to the following paragraphs.
The Implant itself is more for conversation sound frequencies (as I don't have much high frequency sensitivity in my ear), but while riding a bike, I have noticed that the wind noise does make things pretty difficult to be aware of the surroundings. So I tend to check my surroundings far more than an average cyclist does, especially before dangerous bends as I just don't want to risk myself making the wrong move at the wrong time on the country roads. I also cycled with my father and I have noticed that he rarely checks around him as he just simply relies on his hearing.... which isn't always the best thing to do.
So, considering that I tend to look around a fair amount and that wind noise seems to make things slightly hard to pick sounds up at times, I have played music through the Implant itself (there's a wire that plugs to the back of the unit itself) which changes the ratio 60:40 in favour of the mp3 player. So this means that I am able to hear the music a fair bit while still hearing some road noises. But as I still keep checking around me as I am aware of my lack of hearing awareness (as it will always be with me, whether I listen to music or not) as you just cannot relax while on the road (admittedly country roads, but its still relatively dangerous sometimes) and just rely on one senses all the time.
So, for Mike Rotch, my advice would be to simply make sure that he is aware that things are happening around him and just use the music as background noise, not to listen attentively. That is all what music will be, just replacing the background noise to something different that isn't the same noise over and over again.
I kinda fear I've overdone this a bit though....
Oh and before I forget.... I also drive as well (apparently some people assumed deaf or hard of hearing people would have automatically failed the driving test)
