In trying to record the brain's electrical activity off the scalp, he adds, "people assumed that the signal-to-noise ratio and the information content of these signals were limited."

在尝试记录头皮以下的大脑电活动时，他补充说，“人们想当然的认为信号的信噪比和这些信号的信息内容是有限的。”

Nokia has been working with Wolfson Microelectronics of Edinburgh to produce a wireless headset for mobile phones and music players that uses ten MEMS microphones: two to record speech and eight to cancel noise.

ECONOMIST: Noise-cancelling technology

The team analyzed data on loudness, pitch and timbre from just under half a million tracks spanning 55 years, finding the average volume of recordings has increased in that time -- said to be the doing of record labels so songs stand out amongst other radio noise.
