This study assessed the effects of hearing aids on the perception of tinnitus using the Tinnitus Handicap Inventory (THI). THI benefit scores (unaided-aided) were examined in relation to hearing aid benefit as measured with the Abbreviated Profile of Hearing Aid Benefit (APHAB) inventory. The THI benefit was also related to the users' ratings of overall satisfaction with their hearing aids. Thi...

noise interference with employee’s speech communication is considered as one of the noise pollution effect in any workplace. these interferences can disrupt communication of necessary and vital data between individuals. and as a result can cause anything from a slight irritant to a serious safety hazard involving accident or even fatality. this study was focused on the analysis of the human err...

This paper first reviews the state-of-the-art noise reduction methods and points out their vulnerability in noise reduction performance and speech quality, especially under the low signal-noise ratios (SNR) environments. Then this paper presents an improved perceptual multiband spectral subtraction (MBSS) noise reduction algorithm (NRA) and a novel robust voice activity detection (VAD) based on...
