CULLING2004 - Binaural speech intelligibility
Input parameters
| coherence | Maximum of the interaural cross-correlation, the value should be between 0 and 1. |
| phase_target | Interaural phase difference of target signal, between 0 and \(2\pi\) |
| phase_int | Interaural phase difference of the interfering source, between 0 and \(2\pi\) |
| fc | Centre frequency of the frequency channel |
Output parameters
| bmld_output | improvement in predicted signal threshold when phase_target and phase_int differ compared to when they are the same. |
Description
culling2004(coherence,phase_target,phase_int,fc) calculates the binaural masking level difference for a signal in broadband noise. The input noise coherence and phase must be pre-calculated for the frequency channel bearing the signal. See jelfs2011 for an example on how to calculate these.
