I offer you the challenge, given your background, to explain how putting a physical barrier between your inner ear and your surroundings does not bring a level of impairment. [/quote]
Spoken by someone who's never worn headphones?
Challenge accepted!
FACT. Wearing good quality 'earbud' headphones drastically decreases the main cause of impaired hearing whilst cycling, and that's the wind blast noise which is substantial when travelling at 20mph+, and at 30mph+ it's quite uncomfortable without 'protection'.
Therefore JUST wearing them (no audio) actually improves your ability to hear car engines etc etc. Obviously, it's then a balancing act of getting the audio to a level where the earbuds STOP the windblast, but where the audio is not so loud as to reverse the advantage. I'd like to think that my level of audio is bang in the middle, and so is no more 'dangerous' (but admittedly not actually any safer) than not wearing them at all.
I'd also like to think that I wouldn't pass comment without physically experiencing the subject, so if there are folks on here who've never worn headphones they shouldn't really pass comment? Those who do know the score.
To summarise.
No Earbuds.................More dangerous (at high speed)
Earbuds-no audio..........Safer than riding headphone-less
Earbuds-low volume.......A bit better than 'no Earbuds'
earbuds-High volume......More distracting than no Earbuds
Challenge victorious!
Goodnight Springton, there will be no encore.
