Calibration of Relative Level Differences of a Domestic Multichannel Sound Reproduction System

A number of subjective experiments on the calibration of relative level differences of a multichannel sound system are described. The purpose of the experiments was to examine the influence of 1) the calibration signal on the relative level calibration and 2) the relative level calibration on the perceived quality of reproduction of standard audiovisual material. All experiments were conducted using a standardized listening environment and a 3/1 system in a standardized multichannel setup. Three calibration signals were investigated, and the results showed that they did have a significant influence on the calibrated level. The main influence was found to concern the front left and right channels. A series of objective measurements suggested that the subjective calibration is based on a selected frequency range of the spectrum and that the range is determined by the spectral properties of the calibration signal. The relative calibrations obtained in the first series of experiments were tested subjectively using standard audiovisual material. The quality of reproduction of the spatial information and the overall reproduction quality were assessed and the results indicated that the relative level calibration can have a significant influence on both attributes examined.
