A Perceptual Model Applied to Audio Bit-Rate Reduction A model of the human ear has been developed for use in perceptual coding of audio signals. As it predicts well-known experimental results, it is further used as an artificial ear in various experiments on masking phenomena.
A New Perceptual Quality Measure for Bit Rate Reduced Audio
http://www.mp3-tech.org/programmer/docs/AES1996Copenhagen.pdf
A filter bank based perceptual model is presented, which yields better temporal resolution than FFT-based approaches and thus allows a more precise modelling of pre- and post-masking and a refined analysis of the envelopes within each filter channel. 0. Introduction Perceptual audio coding algorithms perform a drastic irrelevancy reduction in order to

Perceptual bit allocation for low rate coding of narrowband audio by Hossein Najafzadeh, Peter Kabal , 2000 In this work we consider adaptive bit allocation for percep-tual coding of narrowband audio signals at low rates (down to 8 kb/s).

Traditional measurement methods like the signal-to-noise ratio are useless to predict the sound quality of low bit-rate audio coding systems. Several perceptual measurement methods have been developed over the last few years. They use a psychoacoustic model to get an estimate of the actual audibility or loudness of coding artifacts. The perceptual models used in these …
