[QUOTE 1724206, member: 45"]Sorry but that's a ridiculous argument.
A deaf person can do nothing about the increased risk that not being able to hear brings. Someone with headphones can.
It's not about should or shouldn't, but about whether the rider accepts the increased risk or not. And there's no getting away from the fact that there is some level of increased risk. Unless you want to argue against physics.[/quote]
Whether you can do something about it or not, the level of risk is the same for both (or greater, even, for a deaf person). So if it's acceptable to cycle whilst deaf, then it has to be acceptable - in itself - to cycle whilst wearing headphones.
A deaf person would be aware that he or she is deaf and would therefore use extra caution and awareness to ensure they were safe. I think I also do that when I wear headphones. I know I'm listening to music, so I make sure I'm aware of everything I possibly can be. Some people wouldn't be, they'd get wrapped up in the music and subconsciously think 'I can't hear a car, so there's not one there'.
I think the lack of conscious awareness is the issue, not the music. If the music makes you forget to be aware, then it's a problem. If it doesn't, then it's fine.
I remember reading a study once that said the majority of women drivers were better drivers when they'd had one drink, than when completely sober. The reason being that they were completely aware that they'd had one drink and concentrated on driving perfectly to make sure they were safe. It's the same principle.
