Measurement of Stereo Soundfield Parameters
Stereo Soundfield Measurements evaluate localization and envelopment of stereo sound systems, and are useful in quantifying spatial audio. This complete sequence measures stereo soundfield parameters such as interaural level difference (ILD) and interaural cross-correlation (IACC) using a Head and Torso Simulator (HATS).
Introduction
The stereo soundfield sequence measures parameters such as Interaural level difference (ILD) and interaural cross-correlation (IACC) using a Head and Torso Simulator (HATS). The spectrum is measured at each ear and calculates interaural level differences (ILD), spectral balance, delay differences, and interaural cross-correlation (IACC). The measurements are made using different time windows, so that the direct, early, late or total parts are separated.
Several different signals are applied to the left and right inputs of the device under test (DUT), and the measurements are made with the HATS left and right ears. Up to 9 measurements in varying positions are made and saved. Results for each position are displayed, and on completion of the testing, means and standard deviations are shown.
