One of the most difficult-to-understand terms for newcomers (and even experienced enthusiasts) in audio and sound reproduction is the decibel, partly because it’s a measure of relative intensity or ...

Megan Gerhart, Au.D. received her doctorate of audiology from the University of Florida. She has experience helping pediatrics to geriatrics both in private practice and medical models of care. She ...

Decibels are commonly used in electronic systems that include RF, audio, and more recently, signal integrity. While many engineers already think in decibels, if you mostly work in the time domain, you ...

From the Richter scale to sound pressure, many modern units utilize the logarithmic “base 10” system. But to many engineers, the decibel (dB) remains one of the trickiest concepts of test and ...

Sounds above 80 dB can cause hearing damage, and we should limit the exposure to prevent hearing loss. Decibel apps are a convenient way to measure volume fairly accurately with your phone. Our ...

Engineers and technicians who work with oscilloscopes are used to seeing waveforms that plot a voltage versus time. Almost all oscilloscopes these days include the Fast Fourier Transform (FFT) to view ...
