acoustic

And the acoustic treatment - not less than $300 but probably not more than $1000.

A rug is an easy win; acoustic ceiling tiles and bass traps are a bit harder...

The first few lines mentioned "acoustic delay lines" which piqued my interest.

Modems were originally, more often than not, used with acoustic couplers.

I've worked in one of these for a happy summer making measurements of acoustic diffuser panels.

A plasma ball is shot in from each end, then 200 steam-driven pistons slam into the container, making an acoustic shock wave that compresses the D-T plasma.

"Thus, a carefully-designed acoustic noise generator would be required for masking the leakage.

It also creates a tactile, acoustic, and olfactory environment.

The technology here is almost certainly acoustic beamforming, and that large square under wraps in the image is an array of small ultrasonic piezo speakers.

So what would be done is that a column of mercury with transducers on both ends would function as speakers and microphones, which in an acoustic medium are the equivalent of read and write heads!The system memory would be a collection of these columns, each I guess storing one bit.

Playing loud music when encrypting/decrypting/typing in your password will defend against acoustic attacks, right?This other type of attack, however, isn't so easily guarded against:Beyond acoustics, we demonstrate that a similar low-bandwidth attack can be performed by measuring the electric potential of a computer chassis.
