Of the vehicles we've measured so far using this methodology, the Genesis Electrified GV70 is the quietest at a 70-mph cruise ...

Accurately measuring output noise and ripple requires a basic understanding of the high frequency nature of noise. Very often, “noise” (as commonly measured) is actually the vector sum of common- and ...

Despite the threat of overfishing in many fish populations, fisheries managers often lack accurate plans and quota systems to allow a sustainable harvest. Traditional methods of estimating fish ...

Nuclear physicists proposed a method to measure the speed of sound characterizing matter created in nuclear collisions. Heavy nuclei consist of hundreds of protons and neutrons (belonging to a group ...

When specifying cooling equipment, engineers are faced with myriad decisions affecting performance and layout. One critical consideration is the noise emitted. As population density rises in major ...

What are the loudest sounds at UB? Where are the university’s quietest spots? What unlikely noises here are around 60 decibels, the level typically associated with a normal conversation between two ...

Martian landers have been able capture measurements of wind speeds -- some gauging the cooling rate of heated materials when winds blow over them, others using cameras to image 'tell-tales' that blow ...

Why You Can’t Just Use a Spectrum Analyzer Industry has an increasing demand for spectrally pure signals in applications such as imaging radar, mobile communications, satellite communications, weather ...

Tsunamis can be incredibly destructive, none more so than the 2004 Indian Ocean Tsunami, the deadliest on record, which claimed nearly 230,000 lives across 15 countries. While we don’t yet have a way ...

Modern digital receiver/exciters (DREX) used in radar and communications systems are capable of significant self-testing in a production factory environment. Long past are the days where the analog ...
