Noise Levels. TX4 Vs Hornet Vs The rest

[adv]

I know I have to compare apples with apples... but I've always wondered about the noise levels on the more expensive helmets. I've never moaned about wind noise and its never really been apparent to me until recently when I swopped from my Suomy to my Airoh S4. 

I understand anything with a peak will have noise, but what makes the TX4 better than the rest?
