Roving-Level, Maximum-Likelihood Procedure for Loudness-Balance Measurement

Abstract

This study focuses on developing a new test procedure for Loudness-Balance experiments. It aims to solve the problem that the standard adaptive procedure does not converge very well for binaural loudness summation. To this end, the standard up-down procedure was replaced by a Maximum-Likelihood Procedure, which was combined with a Roving-Level procedure that employed 10 concurrent tracks. The results for three listeners show that the new procedure appears to solve the convergence problem. It also allows considerable freedom in choosing the levels in successive trials. It offers the possibility of presenting reasonably clear loudness dirrerences thoughout a block of trials and being more efficient that the adaptive, Roving-Level procedure used in a previous study.
