Noise inside helmets can go above 112db or so I read in a test online somewhere recently, most of this noise comes from the back of the helmet strangely enough. Vents and ill-fitting visors also cause some minor attributing noise. There is no helmet that will eliminate such noise totally, all you can do is limit it as already suggested above.
The main problem is worn, compressed or incorrectly fitted helmet liners especially around the neck area, this is where the majority of external noise enters the helmet according to the test.
Properly fitted ear plugs are a must for hearing health if you are concerned about it. Be aware that portable iPod and such simular player’s (basic) ear buds will not protect you, most are ineffective at filtering out unwanted harmful noise, besides I found you end up cranking them way up to damaging levels to hear the sound/ lyrics above the unwanted noise level.
You can buy pro’ musician buds or plugs that have to be moulded to your ear canal shape but are rather exy to have fitted and are very effective.
However the $2 squish and roll foam jobs work well but no guarantees naturally.
