Obviously, noise reduction is a useful tool. These noise reduction techniques are very useful in assuring accurate measurements. Keep in mind that they work best if the signal inputs to the instrument ...

Noise-reduction methods can be grouped into four areas: providing a low-noise, ... so the noise is reduced by the common-mode rejection ratio of the op amp. As previously stated, ...

The new material could be used in cars and manufacturing facilities to reduce traffic and industrial noise. The post Owls ...

If you've seen an owl fly, you probably didn't hear a thing. That's because their skin and feathers dampen sound by absorbing ...

The Prairie-Masker system is a two-part underwater noise reduction system used by U.S. Navy surface ships and submarines. It's designed to make vessels harder to detect by passive sonar, which ...

EPFL researchers have developed a 100% effective, ultra-thin active noise cancelling system that uses an ionized air plasma propulsion system instead of speakers. A 17-mm-thick (0.6-in) layer can ...
