Optimizing Flexible Manufacturing System: A Developed Computer Simulation Model

In recent years, flexible manufacturing system as a response to market demands has been proposed to increase product diversity, optimum utilization of machines andperiods of short-term products.The development of computer systems has provided the ability to build machines with high functionality and the necessary flexibility to perform various operations. However, due to the complexity and the ...

A Psychoacoustic Basis For

Spectral sharpening of speech has been proposed as a possible method for improving speech understanding by listeners with hearing loss. Animal neural physiological data and cochlear models differ in their predictions as to the potential success of spectral sharpening for improved speech recognition. Data from early implementations of spectral sharpening are also ambiguous. Our recent investigat...

Aural Exciter and Loudness Maximizer: What’s Psychoacoustic about "psychoacoustic Processors" ?

In this study two so-called "psychoacoustic processors" are examined exemplarily by applying concepts, models and methods of scientific psychoacoustics. Physical measurements of processed sounds and results of hearing experiments on speech intelligibility and sound quality (Aural Exciter) and loudness (Loudness Maximizer) are presented and discussed with regard to classic psychoacoustic models ...

Psychoacoustic consequences of compression in the peripheral auditory system.

Input-output functions on the basilar membrane of the cochlea show a strong compressive nonlinearity at midrange levels for frequencies close to the characteristic frequency of a given place. This article shows how many different phenomena can be explained as consequences of this nonlinearity, including the "excess" masking produced when 2 nonsimultaneous maskers are combined, the nonlinear gro...
