Just wondering - how many people on this site regularly wear them? I have been on a number of rides with people, but haven't seen people putting in / taking out plugs. For some background reading: http://www.greenleopard.co.uk/story3 http://www.hondahornet.co.uk/earplug.html http://www.isvr.co.uk/at_work/m_cycle.htm http://www.bikexprt.com/bicycle/hearing.htm (bicycle, but applicable) In short, speeds greater than 40 k/hr can create enough wind noise to exceed the 'safe limit' of 85 db(A) for some helmets (this limit is the noise level set by Victorian worksafe for continuous noise exposure). Further, no helmet is perfect - there will always be room for improvement. It is something that I have just started to do as I am riding daily 1.5 hours commuting (which is long enough for ear damage to occur). I am using run of the mill disposable ear plugs, which have an excellent ability to reduce out higher frequency noise (i.e. wind), but only a moderate ability to reduce low to mid range noice (i.e. bike). Therefore I cut the wind, and can still hear my bike and cars around me. I also choose to use these as I have a relatively steady supply of them at work (though these are cheap anyways)... Any thoughts/opinions?
