So an "airbag" inside a "cricket" helmet won't absorb any impact??

"Under BSi testing, the A.C.I.S™ liner consistently outperforms other more traditional polystyrene helmet liners.  When cricket helmets are tested, they are checked by measuring the peak acceleration of a helmeted steel head form falling onto a steel surface.

In these tests, AdiPower helmets combined with the A.C.I.S™ liner can provide as much as 3 times more protection than other leading helmet brands."

Taken from Ayrtek website... Hope Tom doesn't mind


I've read that a helmet can reduce the concussion force (upto 20%) but not eliminate it. The test you quote is the standard drop test and scientist are only beginning to start thinking about helmets and suitable tests to help improve this area of injury. Thankfully a concussion in cricket is rare and possibly risk is higher the faster the ball travels, top edges obviously increase the speed. 

Watch the video on this page if you are still not convinced.

So a standard helmet can reduce concussion by up to 20% ?

And this study you quote is talking about contact sports where physical contact can reach approx 800kg of force as can be seen below.

A far cry from playing a game of non contact game of cricket.

I'm hating the fact that I'm about to quote Ian Chappell, but this one is a good point.
Before the introduction of helmets, every batsman knew if they were going to play particular shots, they had to either:
 a. Make sure you were out of the path of the ball so it would miss you if you missed it, or
B. Play a different shot.

My personal opinion is there are now modern batsman, who have a false sense of invincibility due to their 21st century protective equipment. I know myself when I first started wearing a helmet in the late 90s, I got hit a number of times in my first season, playing shots I wouldn't have pre helmet.
If we saw a return to the pre helmet shots, where batsman got clear, we wouldn't see as many batsman hit.

As for being the safest, I think it's semantics. The brands will continue to leap frog with designs. But with mass produced items, it's almost impossible to guarantee 0% failure rate.

In ongoing test match between Pakistan and New Zealand, Ahmed Shahzad wearing Albion Ultimate 98 got hit on helmet off Corey Anderson's bowling while attempting a pull shot. Got grounded and later CT scan revealed he got a minor fracture.

Here is the video;

So, which helmet should players wear? Which one is safest?

well maybe, but i think you might have misunderstood what those website were saying.

they are talking about repeated impacts causing long term brain injury, we are talking about short term concussion.

cricket helmet undoubtedly help in this very specific task.

You're just plain wrong then.
