Low frequency characteristic parameters measurement of vented-box loudspeaker system using total least squares method
Authors:Xu Boling  Wei Yong
Abstract:The interrelationship between the ARMA model parameters of a vented-box loud-speaker system and lowthequency characteristic parameters is analysed in this paper. These AANA model parameters are deterndned by the total least squares (TLS) method. Therefore, we can measure in the timedomain the fow frequency characteristic parameters of a vented-box loudspeaker system, its impendance curvs and low-frquency response curves. These measured results show a satisfactory agreement with the values obtained by the frequency-domain measurement.
Keywords:ARMA model  Total least squares method  Low frequency parameter  Timedomain Measurement
