Video, Speech, and Audio Signal Processing and ...
The maximum amount of masking produced by the band of noise is 61 dB, while the tone masker produces only 37 dB of masking for a 397 Hz probe. The difference between tone and noise maskers may be more apparent than real, and for ...

Cochlear Implants - Halaman 122
This method takes advantage of the refractory properties of the auditory nerve, measuring the response to a probe pulse with and without a masker pulse preceding it. The theory behind the subtraction method is that if masker pulse is high ...

Auditory Frequency Selectivity - Halaman 181
SIMULTANEOUS MASKING Fig. 1 shows results for a simultaneous masking condition. The masker was 26 ms in duration, the probe 8 ms. The probe was presented during the last part of the masker. The masker level is increased while the ...

Psychoacoustics: Facts and Models - Halaman 105
Besides measurements using two maskers, others have been performed with up to four additional maskers. In this case, it is most effective if each of the four maskers produces the same masked threshold, which should be at least 20 dB above ...

Essentials of Audiology - Halaman 100
First, the amount of masking increases (the curves get higher) as the masker level increases. Second, more masking is produced at frequencies close to the frequency of the masker than at more distant frequencies. For example, the curve for a ...

Oxford Handbook of Auditory Science: Hearing - Halaman 26
As the delaybetween a forward masker and a signal increases, the masker level must be increased to maintain masked threshold. The changes in masker level have to be such that they produce increases in the BM response to the masker ...

The Neurophysiological Bases of Auditory Perception - Halaman 42
The model also fails to predict data for the offfrequency masker (Fig. 4.2). While the measured threshold depends on the masker phase curvature, the model predicts no such dependence. Even if a residual compression of the masker were ...

Auditory Spectral Processing - Halaman 102
Typically, CMR can be defined as the advantage of a coherent masker AM across frequency for the detection of a tonal signal. One example of this advantage can be demonstrated in a band-widening paradigm. In this paradigm, detection ...
