How many accelerometers are required?

A 3-axis accelerometer detects vibrations across 3 axes: X-Horizontal, Y-Vertical, Z-Lateral.

Use one accelerometer to identify the vibration type (T-tire, E-engine, or P-Propshaft
and in which plane the vibration occurs (Vertical, Lateral, Front/Back).

When used with a second accelerometer, compare readings from second location across 1 axis (X or Y or Z).
Or, measure across 2 axes from each accelerometer.

When used with a third and fourth accelerometer, identify and compare vibrations from four locations with each accelerometer measuring across 1 axis (X or Y or Z).

Use the microphone to measure the amplitude of a noise.
Use multiple microphones to compare up to four locations.
