Quiet helmets

and hearing is priceless.

Or some such.

 

It's not volunteers I need, it's a student who wants to do a project
on it. I want to fit microphones into the surface of a helmet and run
it in a tunnel to look at the aerodynamics and noise. It's actually
very similar to the problem of noise inside aircraft cockpits, which
is one reason I'd like to look at it. The problem is that I've offered
it twice as a project and no student wants it.

The pictures are here:

Very roughly, the interesting bit was just how effective or
ineffective windscreens can be (size seems to have little to do with
it).

I'm banned from doing that sort of thing again, because people were
offended by the smell of burning rapeseed oil. Funnily enough.

 

Seriously?

 

Semi-seriously. We're certainly never using rape oil again in that
tunnel.

 

Nice one - cheers Mick.

Style over substance, eh? Where have we heard that before?

 

Same lid as mine. I *have* to wear plugs with it on anything other than very
short journeys!

Nice research, but why did you only used bike with gash colours?

 

I find it certainly helps!

 

Because the volunteers came from ukrm.

 

And they were going so fast the pictures are blurred

 

It was somewhere around Barstow, on the edge of the desert, when the
drugs began to take hold. I remember Dave Swindell

**** me, something we agree on.

I now wish I'd worn earplugs for all the miles I'd done; by the time I
started wearing them it was almost too late. I've suffered more than
just age-related hearing loss, but fortunately have retained enough to
still enjoy music.

Schuberth S1, probably the quietest helmet on the market - but even so
I still use ear plugs and have done so since 1979; graduating from the
EAR visco-elastic foam types to custom-made silicon plugs four years
ago. On hot and or humid days I found that the EAR types would lose
their "recovery" and would fail to seal in the ear canal. No such
problems with the silicon types.

Ergo; NO helmet is "quiet", it is just that some are "quieter" than
others.

Dave Swindell says...

I hate to do this, but I agree with you.

 

20 miles? I use them everywhere, even bimbling into town at lunchtime.

Works on the road, too. I also use them for DIY - hammering, drilling,
using the chop-saw or the belt sander, all that noisy shit. It's not just
the "protecting the hearing" bit: it also makes things that much less
wearing. Snoring, noisy cars, clubbing etc - anywhere that's excessively
noisy, I'll wear them.

 

You mis-spelled "conversing with".

You just don't like hearing the little furry critters scream. Can't say
I blame you but couldn't you get a job on a fishing trawler instead?

 

Nothing much worth hitting on a trawler. I'd find myself going up on deck
with a nine iron and a big box of hamsters...

Somehow I can't imagine you doing that. Cane maybe...

 

Indeed, if only it could be bottled....
