Experimental results plotted as masking patterns: Individual amounts of masking (in dB) as a function of Δ<i>F</i> (in ERB units) with Δ<i>T</i> as parameter.

<p>Note that for the conditions Δ<i>F</i> = 0 that were measured with and without background noise, the thresholds reported here correspond to the condition without noise. The bottom panel shows the mean data. Error bars indicate ±1 standard deviation of the mean data.
