Q. I mean noise of cars, boom boxes, kids bouncing balls on the streets, skateboards and so on...
Answer
Yes, there are two types: Passive noise cancellation (PNC) and Active noise cancellation (ANC).
Active noise cancelling uses electronics to disable sound, more-so the lower noises, something like 500Hz and under. Depending on how good the noise cancelling microphone is, ANC usually gives something like 25-40dB of noise cancellation. A good example of passive noise cancelling headphones would be the Audio-Technica ATHANC-7.
Passive noise cancelling is more associated with earbuds, which make a tight seal around the ear canal to block out ambient noise. The noise cancelling properties aren't limited to only the low frequencies. Some earbuds only give around 20dB of isolation, while canalphones can offer up to 40dB of isolation. A good example of noise cancelling earbuds are Etymotic MC-5.

Noise cancelling headphones?
Q. My dad sings like a strangled cat when he plays guitar and it's driving my sister nuts. I'm in college and I want to get her noise cancelling headphones so she can get some peace and quiet when she's studying. Any recommendations? We've tried earplugs before but she says she still hears the high pitched howling (haha). As for reasoning with him that's out of the question, he thinks he sounds great we've even taped him before.
Thanks!
Thanks!

the best noise cancelling headphones i know are from bose, they are super expencive though. but work like a charm. http://www.bose.com/controller?event=DTC_LINKS_TARGET_EVENT&DTCLinkID=2724&perfsourceid=k108600&src=k108600&OVMTC=standard&OVKEY=bose%20noise%20cancelling%20headphones&OVADID=2674799022&OVKWID=46527510522&OVRAW=bose%20noise%20cancelling%20headphones
i borrow my dad's pair and i can block out the entire world, the headphones create white noise which is why they are noise cancelling. they are the best but you do have to PAY for the best
