The Improvement of Wavelet Packet for Psychoacoustic Model

Advanced Materials Research, 2012
Compared with common psychoacoustic model, this article uses wavelet packet decomposition to decompose a signal. This method improves the situation of insufficient time-frequency resolution which the uniform spectrum analysis causes. In addition, frequency division by wavelet packet decomposition is much closer to human’s critical band than the way ...

Warped DFT as the basis for psychoacoustic model

2004 IEEE International Conference on Acoustics, Speech, and Signal Processing, 2004
We consider the warped DFT as an alternative basis for psychoacoustic models. The appropriate construction of the transform is approached, aiming for precise critical band power analysis. It is shown that sufficient spectral resolution can be obtained for sample block lengths several times shorter than the 1024 or 2048 commonly used in the FFT based ...

Psychoacoustic Modelling of Sound Attributes

SAE Technical Paper Series, 2006
<div class="htmlview paragraph">This study inquired into perceived attributes of car interior noise and correlating psychoacoustic parameters. Auditory assessments of a total of 29 vehicles were performed during cruise and acceleration in two independent road tests. Four perceptual dimensions were found to determine the sound evaluations: comfort/

A Model-based hearing aid: Psychoacoustics, models and algorithms

Proceedings of Meetings on Acoustics, 2013
In hearing aids, amplification and dynamic range compression typically aim at compensating the deficits associated with outer-hair cell (OHC) loss. Nevertheless, success shows large inter-individual variability and hearing-impaired listeners generally still have considerable problems in complex acoustic communication situations including noise and ...

Automatic speech recognition using psychoacoustic models

The Journal of the Acoustical Society of America, 1979
An approach to automatic speech recognition is described, which, in a straightforward way, follows the concept of (1) preprocessing in terms of auditory parameters and (2) subsequent classification and recognition. The preprocessing system has been realized in analog hardware, while recognition is carried out on a digital computer. In the preprocessing

A psychoacoustic model for the noise masking of plosive bursts

The Journal of the Acoustical Society of America, 1997
A model for predicting the masked thresholds of the voiceless plosive bursts /k,t,p/ in background noise is proposed. Because plosive bursts are brief, are generated by a noise source, and have different spectral characteristics, the modeling approach accounts for duration, center frequency, and signal bandwidth.
