They're small-bodied, budget-friendly, inspired by ye olde Rex catalogue pre-War models... Get 'em while they're hot, people ...

Abstract: We consider a broadband bulk acoustic resonator architecture — the so called High-overtone Bulk Acoustic Resonator (HBAR) — as a transducer acting as cooperative target to a RADAR ...

Featuring a solid Sitka spruce top alongside a pickup system and built-in tuner, there’s a lot to enjoy for just $228 ...

Cornell University researchers have finally figured out exactly how human hand claps create their distinctive sound — and ...

A quiet revolution is taking shape in the world of physics, and it doesn’t rely on exotic particles or massive particle ...
