Active Noise Cancellation - does it work?
-
hello people, anyone tried one of those head phone, for example, these ones from Bose[^] with active noise cancellation? Does it work? I hear it's only good with steady background noises. If a baby scream all a sudden Active Noise Tech won't help much. But is this conclusion correct? 1. Active Noise technology good with steady waves forms 2. Active Noise technology not good with transient waves forms

Have you considered the redneck version? Rather than pay over $400 for them, get a pair of earplugs for around 10¢, make holes in them and shove regular headphones through them. Blocks baby screams too, but if you are hit by a truck using them on the road, I accept no responsibility

Years ago I saw a project of one University out there that was about a really small and old car with microphones outside and inside and some new loudspeakers... a computer and a small software... The idea was to make the old and small car sound as a Ferrari or as another car, all in all they were cancelling the real noise the car was doing and adding the noise they wanted... Of course when the driver accelerated the noise was like accelerating and so... it was expensive but cool... :cool:

I can't see that working well. Headphones are easy because the only place you need to get destructive interference is fixed relative to the speakers in the cans; for stand alone speakers you'd end up with the interfering waves ending up in an out of phase making both quiet and extra loud spots. :doh:
Did you ever see history portrayed as an old man with a wise brow and pulseless heart, waging all things in the balance of reason? Is not rather the genius of history like an eternal, imploring maiden, full of fire, with a burning heart and flaming soul, humanly warm and humanly beautiful? --Zachris Topelius Training a telescope on one’s own belly button will only reveal lint.
