Noise Reduction Videos and Sound Tracks
Quiet Ride Full Face motorcycle/snowmobile helmet with Quiet Ride Ear Muffs has been tested by Federal Government and received a NRR (noise reduction rating) of 19 decibels. 19 decibel noise reduction translates into over 65% noise reduction entering ears.

Edited Sound Tracks demonstrating 65% noise reductionin Quiet Ride Helmets

Soundtrack 1

1999 Suzuki 1200 Bandit In -Line 4 cylinder with sound edited. Volume is normal and then electronically turned down 65% (19 decibels)several times during video. This modified video reflects what rider would hear wearing a Quiet Ride Helmet versus standard helmet.

Soundtrack 2

Suzuki RM125 revving engine/noise reduction over 65%


Sound recorder with remote microphone was installed in one ear noise reduction muff to pick up exterior sound from engine before and after ear noise reductions muffs were forced to seal around ears.

In first segment of video rider first puts on Quiet Ride Helmet with music playing through intercom with FM radio.

Second, rider squeezes air pump to force air into bladders between ear noise reduction muffs and inside of helmet shell to force ear noise reduction muffs to seal around ears and block exterior noise from entering ears.  Note, music can be heard much better with 65% less engine noise interference.

Next rider releases bladder air pressure allowing ear noise reduction muff to lose seal around ears.  Engine noise gets louder simulating noise you would hear wearing typical motocross helmet.

Next rider turns off music and removes helmet and engine noise level goes up again.

Edited snowmobile Videos demonstrating 65% noise reduction

Turn up remote speaker volume  to high and experience the 65% drop in sound at some point or points in video to get an idea of how effective Quiet Ride Helmet are in reducing noise.

Yamaha Apex with powerful turbo hill climbing out west in deep snow.  Plenty of  power with plenty of noise. I would estimate at least 110 decibels wide open.  By reducing noise by 65% (18 decibels) in video in a couple of sections I am giving you an example how a Quiet Ride Helmet cold save your hearing and allow your mountain climbing experience to be more enjoyable.   Quiet Ride G8 intercoms in Quiet Ride Helmets would allow for easier communication between riders, an increased safety factor for sever mountain climbing.

Edited Sound Ski Doo Lake Race

This sound modified video of stock Ski Doo is interesting. First the sound of the snowmobile accelerating is not noise, but as the speed increases only wind noise is picked up by the remote video camera mic installed on side of helmet. Wind noise for motorcycles and snowmobiles is a problem. Wind noise decibels over 60 mph can reach over 100 decibels entering ears and over time can cause hearing damage. Quiet Ride Helmets do a good job of reducing wind noise and engine noise with air tight ear muff seal around ears. Yes, if you have enough speed snowmobiles will stay on top of open water, but you had better know what you are doing or you could end up at the bottom of the lake.

Music can be heard over engine noise
 

Helmet speaker when located in ear noise reduction muff will override engine noise when air bladders between earmuff and inside of helmet shell are pumped up with air to force ear noise reduction muffs to seal around ears blocking out interfering exterior engine noise.

Music or communication can be heard at 65 mph using less volume to protect hearing when wearing Quiet Ride Helmets with exclusive noise reduction muffs installed in helmet and helmet speakers installed in ear noise reduction muffs.
