CULLING2004 - Binaural speech intelligibility

Usage

[bmld_out] = culling2004(coherence,phase_target,phase_int,fc)

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.
