Low-Frequency Loudspeaker Measurements with an Accelerometer
Accurate measurements fo the acceleration, velocity, and displacement of a loudspeaker cone can be carried out with the use of a light accelerometer. From these measurements the low-frequency acoustical steady-state performance can be derived. The method is useful in that it dispenses with the need of an anechoic chamber. The accuracy of the measurements permits an easy evaluation of the low-frequency loudspeaker parameters.
