The impact of music and its psychological and physiological changes during exercise is issue that has always been focused on sport science experts. The aim of this study was to compare the effects of musical exercise on aerobic capacity and quality of life in elderly men. This study was conducted on 45 elderly men. The participants were randomly allocated into three groups: aerobic musical exer...

The purpose of this study was to (a) apply the musical sound quality assessment method, Cochlear Implant-MUltiple Stimulus with Hidden Reference and Anchor (CI-MUSHRA), to quantify musical sound quality deficits in CI (cochlear implant) users with respect to high-frequency loss, and (b) assess possible correlations between CI-MUSHRA performance and self-reported musical sound quality, as assess...

N OISE IS A PROBLEM! YOU can't escape it. It is in the environment, electronics used for recording, records, tapes, AM, FM, TV, microwave, and other audio communication media. Noise in studio tape recorders is too high for much of the musical program material being recorded today. Studios without noise reduction equipment usually overcome noise by such undesirable methods as (1) recording at su...

This paper focuses on underdetermined blind source separation (BSS) of three speech signals mixed in a real environment from measurements provided by two sensors. Underdetermined BSS is a problem that has not yet been intensely studied and so far no satisfying solution has been obtained. The major issue encountered in previous work relates to the occurrence of distortion, which affects a separa...

A nonlinear multiband spectral subtraction method is investigated in this study to reduce the colored electronic noise in millimeter wave MMW radar conducted speech. Because the oversubtraction factor of each Bark frequency band can be adaptively adjusted, the nonuniform effects of colored noise in the spectrum of the MMW radar speech can be taken into account in the enhancement process. Both t...

Parametric analysis, modeling, and equalization (inverse modeling) of reverberant and resonating systems find many applications in audio and acoustics. These include room and concert hall acoustics, resonators in musical instruments, and resonant behavior in audio reproduction systems. Estimating the reverberation time or the modal decay rate are important measurement problems in room and conce...

Abstract The simple system composed of three neural-like noisy elements is considered. Two of them (sensory neurons or sensors) are stimulated by noise and periodic signals with different ratio of frequencies, and the third one (interneuron) receives the output of these two sensors and noise. We propose the analytical approach to analysis of Interspike Intervals (ISI) statistics of the spike tr...

A speech denoising technique based on subband noise estimation and a perceptual modification of Wiener filtering is proposed. The noisy speech is first decomposed into critical band signals by an auditory filterbank and the denoising is carried out on the subband signals. The time varying subband noise variance required for denoising is estimated by tracking the minimum variance of the subband ...

Understanding speech in a background of competing noise is challenging, especially for individuals with hearing loss or deficits in auditory processing ability. The ability to hear in background noise cannot be predicted from the audiogram, an assessment of peripheral hearing ability; therefore, it is important to consider the impact of central and cognitive factors on speech-in-noise perceptio...

Currently, most noise reduction algorithms are based on an a priori information such as signal-to-noise ratio (SNR) or noise parameters estimation. They are mostly performed in the spectral domain to reduce the background noise at each frequency bin. However noise reduction in the spectral domain may introduce musical noise and artefacts which are in some cases perceptually more annoying than t...
