sig_vanderheijden1999 - Tone masked by delayed noise(s) with varying ITD
Usage:
stimulus = sig_vanderheijden1999(c_itd,c_sphase,c_noise_mode,c_tone_level,fs,dur,cos_rise_time,bw,fc,spl)
Input parameters:
| c_itd | interaural time difference(s) of the masking noise component(s) (in s) |
| c_sphase | IPD of target tone |
| c_noise_mode | 1 for a single-delayed noise, 2 for opposingly delayed noises (known as double-delayed noise) |
| c_tone_level | tone sound pressure level (in dB) |
| fs | sampling rate (in Hz) |
| dur | duration of stimulus (in s) |
| cos_rise_time | duration of the cosine ramp at start and end of signal (in s) |
| bw | overall bandwidth of stimulus (in Hz) |
| fc | center frequency of inner band noise and the target tone (in Hz) |
| spl | spectral sound pressure level of the noise (in dB) |
Description:
sig_vanderheijden1999 creates a tone masked by either a single delayed noise or two opposingly delayed noises (known as double-delayed noise) with varying ITD.
