Automatic speech recognition using psychoacoustic models
The Journal of the Acoustical Society of America, 1979An 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

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, 2013In 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 ...

Direct MDCT Domain Psychoacoustic Modeling
2007 IEEE International Symposium on Signal Processing and Information Technology, 2007We extend the recently proposed spectral integration based psychoacoustic model for sinusoidal distortions to the MDCT domain. The estimated masking threshold additionally depends on the sub-band spectral flatness measure of the signal which accounts for the non- sinusoidal distortion introduced by masking.

Psychoacoustic Models for Audio Coding
2003In the prior chapter we learned about the limits to human hearing. We learned about the threshold in quiet or hearing threshold below which sounds are inaudible. The hearing threshold is very important to coder design because it represents frequency-dependent levels below which quantization noise levels will be inaudible.

Psychoacoustic Models for Heart Sounds
2011The phonocardiography (PCG) — the art and science of recording and interpreting of heart sounds using latest digital technology has significantly helped us to understand and interpret the complex heart sounds (normal, abnormal sounds including murmurs) and in particular valvular diseases.

Modeling cochlear dynamics: Interrelation between cochlea mechanics and psychoacoustics
The Journal of the Acoustical Society of America, 2010A model of the cochlea was used to bridge the gap between model approaches commonly used to investigate phenomena related to otoacoustic emissions and more filter-based model approaches often used in psychoacoustics. In the present study, a nonlinear and active one-dimensional transmission line model was developed that accounts for several aspects of ...

New psychoacoustic models for avelet based audio watermarking
IEEE International Symposium on Communications and Information Technology, 2005. ISCIT 2005., 2006The new approach to apply psychoacoustic models to the wavelet based audio digital watermarking is proposed in this paper. In the scheme, the additive watermarking technique is used to embed a unique pseudo-random sequence, considered as a watermark, into the transformed domain of audio signal.
