Err... electronic active noise canceling headphones don't work on speech, only against simple droning noises. I'm talking about headphones that use thick pads of material and a strong seal around your ears to straight block sound.
You can just about hear people through them, whisper quiet. But if you are also wearing some in ears, then music, or white noise at a comfortable volume will eliminate it completely.
You want headphones that do like -30db noise attenuation.
- scotty79 13y agoI'm talking about simple passive air defenders that look like large headphones, have seal around the ear and padding. I think those are optimised for noises outside of speech range. After all you want to still be able to hear people while operating heavy machinery.
- shubb 13y agoFascinating. I know the ones I wear work, but they were 'borrowed' from a server room, so might be somehow different... This blog talks about the 'filtering' you describe, completely new to me... http://eardefenders.org/2011/07/filtered-v-s-non-filtered/ http://eardefenders.org/2011/07/filtered-v-s-non-filtered/
