I wonder if there's a noise level meter that I can place the mic up inside these ear cups and get an ambient noise level? .
One of the UK magazines already did this with real helmets on one rider, riding the same loop. The ambient sound level is in fact damaging on a motorcycle, wearing a helmet. They did place a mic right against the ear.
Schuberth was the quietest, by far.
As far as motosports, shooting, airplanes, live concerts, volume is volume. The difference is how loud, what frequencies, and how long. I would proffer that the live concert is the most difficult to protect from damage because of the wide range of frequencies. Much more difficult than the relative constant lower frequencies inside a helmet or in an airplane.
The point I keep trying, obviously poorly, is that to accurately represent the desired musical reproduction inside the ear, while protecting from an extremely loud environment
is exactly what I'm spending money on.
Am I making comment on Westone? No.
Am I saying that after making many other ear monitor purchases, that I have found Sensaphonics to be the best? Yes.
"Custom-fit, soft-gel silicone earpieces
provide superb noise isolation (up to -37
dB), which makes the 2MAX the quietest
headphone Playback has ever tested—
regardless of type. Note that the 2MAX
provides backgrounds said to be as much
as -10dB quieter that those afforded by
competing monitors, which is—trust us on
this one—a very significant difference."
The Big Ear monitors ($350) I own are basically rebadged Westones, the ones with dual drivers and vinyl ear pieces (as I recall).
If the desired goal was purely protection, or isolation, then that is a different discussion.
The addition of cups around the ear might be good. The single biggest consideration with a full face helmet, with the visor shut, is the neck area. If you want to add a great deal of isolation, wear some sort of neck sock to further shield the area where the helmet foam meets the skin.
I think that the Schuberth design has the smallest neck opening, making for a more quiet environment. In severe crosswinds I can position my head, up down/side to side, in a manner that makes the helmet much quieter.
