Decibel Reading #2

... The decibel is not an SI unit, although the International Committee for Weights and Measures (BIPM) has recommended its inclusion in the SI system. The d is therefore lowercase, as it is the SI prefix deci-, and the B is capitalized, as it is an abbreviation of a namederived unit, the bel, named for ...

... Consider a sine wave viewed in the time domain – that is, amplitude vs. time – as might be seen on an oscilloscope. This alternating current waveform’s amplitude or level can be characterized in a variety of ways. One can measure the sine wave’s peak-to-peak, peak, root mean square or average values ...

... Note that the voltage and current expressions are just like the power expression except that they have 20 as the multiplier instead of 10 because power is proportional to the square of the voltage or current. Exercise: How many decibels larger is the voltage of a 9-volt transistor battery than that ...

... Sound intensity or sound pressure level (SPL) is also specified in dB. In this case, the reference level of 0 dB corresponds to a pressure of 0.0002 microbars which is the standard threshold for being able to hear a sound. As the sounds get louder, the value of SPL in dB also increases, indicating a ...
