Sounds that are lower pitched are less studied than other types. Some say it’s a health hazard. Others have doubts. By Lourdes Medrano/Undark Published Apr 17, 2024 8:00 AM EDT This article was ...
The design halves the width of material needed to absorb low-frequency noise, making it practical for real-world applications ...
Silicon-carbide (SiC) MOSFETs allow for switching at higher voltage and current. SiC MOSFETs enable low switching losses and higher operating temperatures. The SiC MOSFET’s fast switching speeds ...
Most oscilloscopes are fitted with filters to help improve measurement by reducing overall noise in an acquisition to improve signal-to-noise ratio (SNR). Even the most basic oscilloscopes include an ...
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.
