For all the suggestions of headphones. They're nearly ineffective. and Ive had BOSE QC25s before and i'm pretty sure NC technology is useless for non patterned sounds (language is unpredictable as far as NC is concerned). NC is good for things like motors, fans, rivers etc that have more or less the same sound continuously.
