Scientists Levitate Objects With Sound


Yoichi Ochiai, Takayuki Hoshi and Jun Rekimoto – scientists at the University of Tokyo – have created a way to levitate objects, in a very precise way, using sound.

An ultrasound standing wave is capable of suspending small particles at its sound pressure nodes. This method has been used previously to levitate lightweight particles, small creatures, and water droplets.

The new system uses a three-dimensional array of speakers, allowing for controlled levitation & movement of objects.

Here’s a demo of the three-dimensional acoustic levitation in action: Continue reading

KRK ERGO Room Correction System Shipping

KRK Ergo

2009 NAMM Show: At last year’s NAMM show, we were impressed by the technology behind KRK’s ERGO (Enhanced Room Geometry Optimization) room correction system.

It’s a system that automatically measures the acoustics of your listening room and adjust/corrects the output of your monitors to compensate. (See our video demo of the KRK ERGO system).

Just in time for this year’s show, KRK Systems has announced worldwide availability of ERGO. (It was originally expected in April of 2008). The ERGO system retails for $799.
