Pillow without snoring

However, such systems are not very practical. To begin with, they are cumbersome: if you go on vacation with the whole family, you are unlikely to grab the headboard with built-in speakers and microphones. In addition, the system at the head of the bed provides effective suppression of snoring only at certain points of intersection of sound waves. In addition, they cannot always coincide with the position of your head.
In the US created a pillow that fights snoring.

It contains a noise reduction system that adapts to the sounds and produces sound waves that neutralize snoring. Designed pillow for someone who sleeps next to snoring.
Scientists from the University of Northern Illinois (USA) have come up with this. They built a compact noise cancellation device into the pillow. It consists of three microphones, speakers and a sound filter. The first microphone (main) highlights the sounds characteristic of snoring from the general acoustic background. The other two correct possible errors. The speaker inside the pillow emits an anti-noise signal, that negates your neighbor’s bedside nightly trills. The device determines the source of snoring and radiates in its direct sound waves with the same amplitude, only turned in phase. As a result, the waves are mixed, suppressing the sound of snoring. A similar principle, by the way, is used for noise cancellation in headphones and other acoustic systems.

Researchers have developed similar systems before. Only they were not so compact and comfortable. Usually, they were a set of a microphone, sound filter, and speakers, built into the head of the bed. However, such systems are not very practical. To begin with, they are cumbersome: if you go on vacation with the whole family, you are unlikely to grab the headboard with built-in speakers and microphones. In addition, the system at the head of the bed provides effective suppression of snoring only at certain points of intersection of sound waves. In addition, they cannot always coincide with the position of your head.

Another thing – the pillow. If you wish, you can cram it into a suitcase, and the source of unpleasant sounds will always be in close proximity to it. Or rather – on it.
