The LectroFan noise machine, which has a USB plug-in for power, offers 10 unique and non-looping fan sounds and 10 levels of ...

May the best noise win. In a world of cacophony, it may be too much to ask for silence. Even that, as Simon and Garfunkel warned us, has sounds. So what do you do? Counteract sound with sound. Set a ...

Noise is an annoying but unavoidable part of any engineering project. Fixing noise issues is hard enough, but even just measuring how much noise an amplifier adds to your signal is tricky without ...

This video shows how to measure RIGOL DSA815’s phase noise. It also includes a brief explanation on the basic principles of phase noise specification. In the experiment, the DG4000 arbitrary waveform ...

Are you sick of tossing and turning at night? Uncover the science behind the different noise colors. You may be a white noise or brown noise sleeper. I frequently toss and turn at night. If a breeze ...

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 ...

Electrical noise, like taxes, is always with us. Most of the time noise is small and we can ignore it, but there are some measurement circumstances where noise must be dealt with. What can be done to ...

This file type includes high-resolution graphics and schematics when applicable. The biggest problem with precision noise measurement is that the noise floor you’re trying to evaluate is frequently ...

People can describe noise using color, similar to how they may describe light. Two colors of noise are pink and white, which may have many potential applications, such as aiding sleep. A person can ...
