Automated Measurements of Loudspeaker Small Signal Parameters

Authors: Cabot, Richard C.

AES Convention 81 · Paper 2402 · November 1986

Abstract

A computer controlled system for measuring small signal parameters of loudspeakers will be presented. The system uses a signal generator, voltmeter, phasemeter, and ohmmeter to measure the free air resonance frequency and Q. The loudspeaker is placed on a box and the measurements are automatically repeated. These measurements, in conjunction with a voice coil resistance measurement, give all of the information needed for calculation of the loudspeaker parameters. The program calculates and prints the values. A flowchart and a listing of the BASIC language program are given. Examples of the measurements will be presented.
