Long-term exposure to low-frequency noise can cause numerous health problems, but the solution may be found in an unexpected object, a pingpong ball. Conventionally thought of as the hollow plastic ...
In a study published in Science Advances, researchers from Technical University of Denmark and Universidad Politécnica de Madrid demonstrate a new device called an acoustic rainbow emitter (ARE) that ...
In a video demonstration, Microchip Technology’s chip-scale atomic clocks reveal their low phase noise and application ...
Researchers describe an acoustic meta-surface that uses pingpong balls, with small holes punctured in each, as Helmholtz resonators to create inexpensive but effective low-frequency sound insulation.
