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 ...

Engineers are rewriting the rules on how car cabin noise is measured
For decades, carmakers treated cabin noise as a single number problem, something to be tamed with thicker glass and extra ...
Forget hunting for a tape measure or a protractor. Use your Android phone camera and sensors to handle different types of measurements easily.
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 ...
Three tools are typically used to measure vibrational noise (noise) - a storage Oscilloscope (scope); a vibration sensor (sensor), which is generally a 'seismic grade' accelerometer 1; and a ...
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 ...
Researchers have devised a revolutionary new technique for measuring the microscopic elasticity of materials. Known as SRAS, the technology works by measuring the speed of sound across the material's ...
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 ...
