The team tested the system in an ordinary room with real echoes to show that it could function in the actual world, such as in classrooms, cars, or outside. At the moment, the system can transmit sound to a target roughly a meter away at 60 decibels, which is the average volume of a spoken conversation.

To improve the range and volume, the team proposes increasing the power of the ultrasound beams. Achieving that goal would drastically change how people use sound by providing a greater degree of privacy and personalization in public environments.

Superconductive materials seem miraculous. Their resistanceless flow of electricity has been exploited in some powerful ways—from super-strong magnets used in MRIs, particle accelerators and fusion plants. And then there’s, their bizarre ability to levitate in magnetic fields. But the broader use of superconductors is limited because they need to be cooled to extremely low temperatures to work. But what if we could produce superconductivity at room temperature? It would change the world.
