Title:
音響測定の現場補償方法
Document Type and Number:
Japanese Patent JP7064220
Kind Code:
B2
Abstract:
The present disclosure relates to a method for estimating one or more compensation parameters from impedance measurements of an acoustic load. The method comprises a series of steps including providing a probe assembly measurement setup and the disclosure also relates to a system to perform impedance measurements. The compensation parameters are estimated through a minimization process, preferably minimizing an error estimate of a first real and second imaginary part of the reflectance. The resulting compensation parameters are used to restore causality of the reflectance and accordingly provide more accurate impedance measurements.
