Why should you need a db?
If you want to express large numbers of ratios with small values you will like the decibel. 1000 volts means 60 dB. The reference 0 dB = 1 volt. 0.001 volt means -60 dB.
How loud is 69 db?
Since the db scale is relative, it depends on what 0 db means. Typically, however, 69 db is a very soft sound, almost a whisper.
What does the abbreviated science term db means?
db stands for Decibel and it means a unit used to compare the loudness of different sounds :D
What does dB equals to?
dB (decibel) is a logarithmic measure of the ratio of two power values, for example, two signal strengths. This is often used for power gain or power loss. For example, a loss of 10 dB means that the signal degrades by a factor of 10, a loss of 20 dB means that the signal degrades by a factor of 100, and a loss of 30 dB means that the signal degrades by a factor of 1000.
If gain is 10 db what is the ratio of voltages?
10 dB gain means a voltage ratio of 3.16227766 to 1.
