WebPsychoacoustic methods were used to measure the changes in behavioral thresholds due to the presence of a masker of the opposing modality. Subjects were stimulated electrically with unmodulated pulse trains using a research interface and acoustically with pure tones delivered via headphones. WebAt the same time, the frequency domain masking effect for human auditory perception is considered, and we show that, be referring the psychoacoustic model in the spectrum, the subjective auditory dynamics of the audio file can be improved. The psychoacoustic model in this thesis is based on the techniques for MPEG-1 audio compression.
