Tips to reduce noise level in helmet

[Cormanus]

I usually use noise isolating in-ear headphones. Serves as an ear plug and music/phone/intercom source in one. Excellent noise reduction, but the only problem is that depending on volume, you can't hear emergency vehicles.

Me too. Pterodactyl put me on to them. They are at least as good or better than earplugs and mean I can hear a GPS on the occasions I need to use one.

It's worth heading Ferret' wise words too—

Yes it does Rob. Shooting guns as a kid, listening to rock n roll as a teen and sub adult, riding street bikes without earplugs for 50 years and racing 2 stroke motorcycles for 10 years has taken a terrible toll on my hearing. Pretty loud ringing 24 hours a day 7 days a week 365 days a year is the result. At this point the air noise at speed actually drowns out the ringing giving some relief from that. Imagine wanting loud air noise so you don't hear the ringing. Sad. You do learn to pretty much ignore it, otherwise you'd never sleep, but I'd really rather not have it in the first place, and wish I had protected my hearing my whole life.

I would recommend anyone who's ears are not ringing now, wear some ear protection in any loud environments, including riding a motorcycle.
