Dear All,
The concept of
masking thresholds depends on a priori knowledge of the signal that will be masked leading to differences in masking thresholds for noise like and sinus like degradations.
A better approach is to calculate internal representations that take into account time frequency spreading and inhibition. This approach is used in POLQA

Dear Mengli,
If you are interested in accounting for both spectral and temporal auditory masking effects, you could have a look at this paper:
https://doi.org/10.1371/journal.pone.0166937
It is about a joint time-frequency masking model I’ve worked on in the past. A Matlab/Octave script that allows to compute the masking function is provided as supplementary material.
I thought it may help!
Best regards,
Thibaud.

Thanks very much for the code!
I did the same thing using ISO psychoacoustic model 2. Was thinking about using models to account for temporal effect. Have you tried more advanced auditory models?

I´m currently working on something similar and I´ve been developing on top of the code and psychoacoustic models based on:
ISO/IEC 11172-3:1993, Information technology – Coding of moving pictures and associated audio for digital storage media at up to about 1,5 Mbit/s – Part 3: Audio
Hoping this is of some help to you.
I am trying to convert masking curves into the frequency responses of the original maskers (single speech sounds). The maskees I am using are narrow band noises at different frequencies.
It has taken me enormous effort to find an auditory model to make accurate predictions, considering the maskers are complex tones with multiple harmonics in high frequency region. Might anyone provide some guidance or
advice on finding a suitable model?
Is it even possible to do such prediction knowing only the frequency responses of the maskees and the masking thresholds given that temporal effects would inevitably appear because of the higher harmonics in human speech
sounds? Any opinions?
Any suggestion would be greatly appreciated!
