If you're looking for quiet helmets, I can recommend the HJC RPHA-MAX and the Schuberth C3 Pro. Those are the two quietest modulars I've ever tried. I have tried a lot of helmets for demo rides - I use calibrated 4mm microphones mounted on in-ear plugs, and record the noise level on a 10 minute ride in traffic in-town and on the freeway, ranging in speeds between 0 MPH and 75 MPH. The C3 Pro came in the quietest (around 84 dB SPL peak at 75 MPH, typical 71 dB SPL at 30 MPH in town), and the HJC was just 1.1 dB louder. All others I've tested were at least 3 dB louder than the HJC.
