What is psychoacoustic masking?
When multiple sounds are played at the same time, a psychoacoustic phenomena called masking comes into play. Masking explains why it's so hard to clearly hear the timbre of two sounds with overlapping frequencies. Masking explains why it's so hard to clearly hear the timbre of two sounds with overlapping frequencies.
What is psychoacoustic tuning curves?
A common method to determine the best masker frequency to mask an external sound is called psychophysical tuning curve (PTC). A PTC represents the level of a narrowband masker required to just mask a fixed signal as a function of the masker frequency.
What is psychoacoustic phenomenon?
Psychoacoustics is the scientific study of sound perception and audiology. This includes speech, music, and other sound frequencies that travel through our ears. Knowing the limits of human hearing is a good way to familiarize yourself with psychoacoustics.
What is psychoacoustic modeling?
A psychoacoustic (perceptual) model is used to analyze the input audio signal and determine relevant perceptual signal aspects, most notably the signal's masking ability (e.g., masking threshold) as a function of frequency and time.
