HUMAN TIME – FREQUENCY ACUITY

An interesting study about the human’s perception and judging of the frequency and timing of the sound. Below is an expert from the study and the link to the PDF…

Jacob N. Oppenheim, Marcelo O. Magnasco: “The time-frequency uncertainty principle states that the product of the temporal and frequency extents of a signal cannot be smaller than 1/(4?). We study human ability to simultaneously judge the frequency and the timing of a sound. Our subjects often exceeded the uncertainty limit, sometimes by more than tenfold, mostly through remarkable timing acuity. Our results establish a lower bound for the nonlinearity and complexity of the algorithms employed by our brains in parsing transient sounds, rule out simple “linear filter” models of early auditory processing, and highlight timing acuity as a central feature in auditory object processing.”
