If an acoustic variable ranges from 55 to 105, what is its amplitude?

Explanation:
Amplitude is the maximum deviation from the baseline, equal to half the range of the signal. Here, the variable spans from 55 to 105, so the range is 105 − 55 = 50. Half of that is 25, which is the amplitude. The midpoint is 80, so the waveform rises 25 units above and falls 25 units below that center. The other values (105 as the top, 55 as the bottom, and 50 as the full range) are not the amplitude.
