Psychoacoustics: Facts and Models

  title={Psychoacoustics: Facts and Models},
  author={Hugo Fastl and E. Zwicker},
This description of the processing of sound by the human hearing system presents the quantitative relationship between sound stimuli and auditory perceptions in terms of hearing sensations, and implements these relationships in model form. Modern views are outlined of peripheral activity in the inner ear, which plays an important role in the development of many hearing sensations. The dependence of these sensations on acoustic parameters is described in psychoacoustical terms. 
Principles of Psychoacoustics
A good understanding of the sensory response of the human auditory system is essential to the development of psychoacoustic models for audio watermarking, where the perceptual quality of processed audio must be preserved to the greatest extent.
Perception of Speech and Sound
The transformation of acoustical signals into auditory sensations can be characterized by psychophysical quantities such as loudness, tonality, or perceived pitch. The resolution limits of the

Psychoacoustics deals with the perception of acoustic noise by the human hearing. For more than 20 years the main practical applications of psychoacoustic perceptions have been located in the range
Sound, Speech, and Hearing
The basic physics of sound is first developed, including that of sound wave propagation in air and at interfaces, and of sound in resonant cavities, and these concepts are then applied to speaking
Psychoacoustic analysis of pneumatic switching valve noise
Acoustic is the well-known science of sound and its propagation in air. Psychoacoustic though is an incipient part of acoustics that deals with the effect of the humanly perceived sound. Acoustical
Environmental noise assessment: Psychophysical background
In this paper, some aspects of the psychophysical background of environmental noise assessment are touched. Psychophysical methods useful for the measurement of environmental noise are mentioned. The

Systematic and progressive experiments using psychoacoustic methods will help to move "out of the ideal and in to the real" to gain a more complete view of potential auditory-masking effects in marine mammals.
Psychoacoustic Models for Audio Coding
The hearing threshold is very important to coder design because it represents frequency-dependent levels below which quantization noise levels will be inaudible, and the implication in the coded representation of the signal is that certain frequency components can be quantized with a relatively small number of bits without introducing audible distortion.

The presented human ear model overcomes restrictions because of the physiological modelling approach of sound processing in the ear, which is valid, independent from the signal characteristics, and indicates that psychoacoustic observations in terms of loudness and masking are closely met.
Auditory modelling for speech processing in the perceptual domain
This work presents a new computational model for the auditory system by exploring the psychoacoustical masking properties of the human hearing system, and the model is then applied to speech coding in the perceptual domain.
