Decibels (dB) are a unit for measuring sound. Since sound reproduction is critical for the home theater experience, it's important to understand the meaning of decibels when it comes to music.

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 ...
