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 ...

In Decibels: Use with caution, I reviewed the concept of decibels as a ratio of two powers (and sometimes voltages). Decibels are also used to indicate absolute power and voltage levels by specifying ...

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 ...

Noisy environments can significantly and negatively effect our bodies, and are a great villain to concentration, learning, and productivity in classrooms and offices. Headaches are one momentary ...
