How do we measure pitch and volume?
We measure pitch with frequency and volume with amplitude.
How do you determine the ratio of an amplitude?
Amplitude ratio to dB conversion:For amplitude of waves like voltage, current and sound pressure level:GdB = 20 log10(A2 / A1)A2 is the amplitude level.A1 is the referenced amplitude level.GdB is the amplitude ratio or gain in dB.dB to amplitude ratio conversion:A2 = A1 · 10(GdB / 20)A2 is the amplitude level.A1 is the referenced amplitude level.GdB is the amplitude ratio or gain in dB.

What is amplitude ratio?
A measure of the strength of a wave is its amplitude which is the vertical distance between the heights of the wave's peaks and the heights of its troughs. An ocean wave might be said to be 20 metres high, for instance, meaning that an observer can see that the bottom of the wave is 20 metres below the top of the wave. The amplitude of that wave would be 20 metres. If you wanted to compare two waves you could use their amplitude ratio, simply the ratio of their two amplitudes.
What is the standard unit of amplitude?
As radio frequency, in would be modulation in hertz, kilohertz, megahertz. In other areas of measure it could be peak-to-peak. I.E. the maximum absolute value of some quantity that varies, usually with regular frequency. The unit of amplitude depends specifically on the type of wave, certain mechanical waves (e.g. those in in a plucked guitar string) have amplitudes measured in metres. Pressure waves (such as sound) have the unit of pressure as their amplitude (Pascals) where as electromagnetic waves use the electric field strength in volts/metre as the unit of amplitude. As you look at an oscilloscope, the vertical peak of a waveform From Wikipedia: The maximum absolute value of the vertical component of a curve or function, especially one that is periodic.
