If you’ve hung around electronics for any length of time, you’ve surely heard of the decibel (often abbreviated dB). The decibel is a measure of a power ratio. Actually, the real measure is a bel, but ...

Termination resistors and the ratio units of voltage and power — dB — are interrelated topics. The dB units can refer to voltage or power, and conversions between voltage dB units and power dB units ...

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 ...

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 ...

SBE certification is the emblem of professionalism in broadcast engineering. To help you get in the certification exam frame of mind, Radio World Engineering Extra poses a typical question in each ...

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 ...

Q: Can someone please explain the relationships between watts and dB's to me? I am new to audio and wish to acquire a better understanding of power/watts, etc. Thanks. A: Decibel (dB) (1) a ...

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 ...

For those looking to gain a deeper understanding of how audio works, whether to make better-informed decisions or simply for the sake of curiosity, it's useful to lay down some ground rules that ...

Editor's Note: We have strived to maintain accessibility in our Bring Science Home activities by limiting the required technology. We recognize technology is now more widely available than it was when ...

A logarithm is a mathematical operation that determines how many times a certain number, called the base, is multiplied by itself to reach another number. Because logarithms relate geometric ...
