The branch of psychoacoustics examines the concept of auditory masking and its effect on compression. Within each subband where blurring occurs the presence of a strong tonal signal can mask a region of weaker signals. This is evidenced in the following figure. If the noise resulting from approximation of sound data ...

WebFeb 1, 2024 · Psychoacoustic ANC reduces noise in the most sensitive frequency range for human’s hearing system, 0–4000 Hz, and masking operates in order to mask out residual and high-frequency noise. In additional, proposed noise reduction system reduces only audible noise components.
WebAbstract: This paper presents the test results of analyzing mel frequency cepstrum coefficient (MFCC), delta and difference cepstrum features to detect and distinguish the truthful and deceptive speech. The features are extracted based on the psychoacoustic masking property of human speech and how it is perceived. Truthful and deceptive …
