Amazing hearing protection - Bose 30 earphones

[Ulvetanna_imp]

Question for those who might know...does 'noise canceling' have the same protective effect as blocking the noise via earplugs? Or does it just trick you into not hearing the noise while the ear drums still get bombarded?

Reverses the phase of the frequency which is coming from outside the earbud/phone. Completely cancels the energy of that frequency.

Very effective. You will NOT hear any vehicles approaching you. Those pesky sirens you'd hear when the fire trucks are bearing down on you to save your home burning to the ground won't interrupt the reveries of sweet, sweet music.

I am sure y'all gather I am not a fan of blocking the hearing in this way. Attenuation, not cancellation, is what we want. Not being able to hear emergency vehicles or other important ambient sounds, not good.

Noise cancelling is not legal, but soft earplugs are OK in CA now, though. I've never had any problem hearing emergency vehicles with these in my ears.

Yes, I'm not interested in sound blocking. I'm an all-the-time earplug wearer, and I do have helmet speakers for music, but never at a level that interferes with critical external sound. I just want the wind noise decreased.

Great for pilots who hear everything they need to hear through the headset, not great for us riders who need to hear ambient noise that can be a threat.

The noise-cancellation works by the headset's external microphone comparing the external sound frequencies to what is being piped into the speakers. Anything doesn't match perfectly, the headset generates a perfect replication out of phase, which completely negates the objectionable sounds. It uses a computer for this. However sound can still seep through if the headphones or earbuds don't seal perfectly, it all depends on how effective the seal is between the ear and the headset. It's not perfect. Isolation headphones are the best choice for ear protection, like you would use for flying or shooting.

Your method is the best, attenuate the sound, use external speakers, you can still hear the emergency vehicles, etcetera.

The 3M soft foam plugs I use cut up to 32 dB which is very good.
