  Psychoacoustics - Hydrogenaudio Knowledgebase
The psychoacoustic model provides for high quality lossy signal compression by describing which parts of a given digital audio signal can be removed (or aggressively compressed) safely - that is, without significant losses in the quality of the sound.
Psychoacoustic analysis routinely leads to compressed music files that are 10 to 12 times smaller than high quality original masters with very little discernible loss in quality.
Psychoacoustic models are based heavily on human anatomy, especially the ear's limitations in perceiving sound as outlined previously.

  Psychoacoustics - Wikipedia, the free encyclopedia
Psychoacoustics is the study of subjective human perception of sounds.
Psychoacoustics is based heavily on human anatomy, especially the ear's limitations in perceiving sound as outlined previously.
Psychoacoustics includes many subjects and produces discoveries which are relevant to music and its composition and performance, and some musicians, such as Benjamin Boretz, consider the results or some of the results of psychoacoustics to be meaningful only in a musical context.

 [No title]
  Psychoacoustics studies the relationship between acoustic sound signals, the auditory system physiology, and the psychological perception to sound, in order to explain the auditory behavioral responses of human listeners, the abilities and limitations of the human ear, and the auditory complex processes that occur inside the brain.
Psychoacoustics demonstrates how remarkable the human auditory system is in terms of absolute sensitivity and in terms of the range of intensities to which it can respond.
In psychoacoustics, the term pitch is considered to be the psychological perception of frequency.

 illumin : printable : The Basics of Psychoacoustics with Respect to Localization   (Site not responding. Last check: 2007-10-08)
Since the hearing process is both psychological (associated with the brain) and acoustical (associated with the physics of sound), it is commonly referred to as psychoacoustics.
Psychoacoustics, or the study of human perception of sound, provides an explanation of how the human ear-brain system interprets sound and decodes information from a pair of receivers (ears) into a complete, 3-dimensional auditory 'image'.
By utilizing their understanding of psychoacoustic localization principles and the methods by which the ears work, sound system designers for film, music, and video games will be able to efficiently create simulative and immersive experiences for listeners.

The objective of research in psychoacoustics is to understand the relationship between the physical characteristics of a sound and the perception of the sound by a human listener.
Psychoacoustic models are used in audio coders to predict which elements of a sound are likely inaudible.
Psychoacoustic models aid in optimizing the performance of audio processing and measurement devices.

 Howard Wright: research on the acoustics and psychoacoustics of wind instruments
My research project is on the psychoacoustical analysis of wind instruments, particularly those classified as `lip-reed' instruments, such as the trumpet and trombone.
Psychoacoustical work, which examines subjective attributes such as pitch, loudness and timbre, provides a means of linking subjective musical judgements of an instrument's sound with physical measurements, such as frequency response curves.
The results of the psychoacoustical tests will show the amount by which the partial amplitudes must be changed before distinct changes in tone quality are perceived by the listener.

 The Power of Sound > Psychoacoustics
In the realm of psychoacoustics, the terms music, sound, frequency, and vibration are essentially interchangeable, because they are different approximations of the same essence.
Psychoacoustics is also the over-arching theme of his book, The Power of Sound: How to Manage Your Personal Soundscape for a Vital, Productive and Healthy Life (Healing Arts Press, 2001).
Per Dr. Alfred Tomatis — widely considered to be the grandfather of modern psychoacoustics — sound is a "nutrient for the nervous system." With this context in mind, the author endeavors to provide a 21st century user's manual for the human auditory system.

 Ecological Psychoacoustics is available from Bestprices.com Books!
However, the chapters in Ecological Psychoacoustics suggest many reasons why combining the rigor of psychoacoustics with the relevance of ecological perception could improve significantly the understanding of auditory perception in the world of real sound sources.
Psychoacoustics has produced a wealth of knowledge about sensory processing of simple sounds, especially by the auditory periphery.
Ecological Psychoacoustics examines recent work that challenges some of the traditional ideas about auditory perception that were established with these impoverished stimuli and provides a focused look at the perceptual processes that are more likely to occur in natural settings.

The group of infants who listened to Brahms gained weight faster, had fewer complications and were released from the hospital an average of a week earlier than those babies who did not listen to Brahms.
Psychoacoustics is in its infancy, and we are only now beginning to understand the precision in which sound patterns can affect brain and cellular processes.

 What is Psychoacoustics?
Psychoacoustics is not concerned with how sounds produce a particular emotional or cognitive response.
Having said that, psychoacoustics is a very broad area, and while there is a large overlap with physiology at one end, at the other end we sometimes have to appeal to mainstream psychology in order to account for our more complex experimental results.
Many readers might be disappointed at this point to discover that psychoacoustics is not about sonic mind control, although if you have ever done one of my experiments you might appreciate the effect of extreme boredom on the will to live.

 Timbre: Mental: Psychoacoustics
The characteristics of a recording that influence our perception of space and overal "realism" are collectively referred to as "psychoacoustics." Stereo was an early attempt to improve the psychoacoustics of consumer recordings by confining sounds from the left to the left speaker and sounds from the right to the right speaker.
The result is uncannily realistic, provided that the listener uses headphones, and also that his or her ear flaps are roughly the same size and shape as the dummy’s.
We build that subjective model psychoacoustically, using the most primordial of our senses (touch, elaborated as hearing), and then project it into a virtual reality "outside" that is, for all intents and purposes, the real world.
