The subjects' mean 50% thresholds of 2-stream responses and corresponding modelled excitation patterns.

<p>The subjects' mean 50% thresholds of 2-stream responses calculated from observed data (dark colours) and modelled excitation patterns (pale colours). The panels show data for different carrier frequencies (<i>f_c</i> in columns) and modulation depths (<i>m</i> in rows). The data is grouped by tone pattern (shortly denoted as TD/SOA_across; colours), and labelled with the reference modulation frequency in Hz within each group. The error bars denote the standard error. The arrows mark the three conditions used to fit the model data to the observed data.
