Applied Psychoacoustics
Psychoacoustics is presently applied within many fields from software development, where developers map proven and experimental mathematical patterns; in digital signal processing, where many audio compression codecs such as MP3 use a psychoacoustic model to increase compression ratios; in the design of (high end) audio systems for accurate reproduction of music in theatres and homes; as well as defense systems where scientists have experimented with limited success in creating new acoustic weapons, which emit frequencies that may impair, harm, or kill. It is also applied today within music, where musicians and artists continue to create new auditory experiences by masking unwanted frequencies of instruments, causing other frequencies to be enhanced. Yet another application is in design of small or lower-quality loudspeakers, which use the phenomenon of missing fundamentals to give the effect of low frequency bass notes that the system, due to frequency limitations, they cannot actually reproduce (see references).

Famous quotes containing the word applied:
“Those who dare to interpret God’s will must never claim Him as an asset for one nation or group rather than another. War springs from the love and loyalty which should be offered to God being applied to some God substitute, one of the most dangerous being nationalism.”
—Robert Runcie (b. 1921)
