Available in PDF, EPUB and Kindle. Book excerpt: Wind noise is problematic for hearing aid users who enjoy outdoor activities. Not only is it annoying, it can create distortion by overloading the microphone and masking signals that hearing aid users desire to hear. Some hearing aid manufacturers offer wind noise reduction in addition to general noise reduction (WNR + NR) for clinicians to manipulate in their software. This study compares objective and subjective measures of wind noise reduction as well as subjective measure of intelligibility obtained using various hearing aid manufacturers and noise reduction settings while HINT sentences were played in the presence of constantly generated wind. Significant differences in the subjective and objective amount of noise present and perceived speech intelligibility was found both between manufacturers and between noise reduction settings for each manufacturer. Subjectively, intelligibility and noisiness were positively correlated (r=0.74, p>.001); conditions that were perceived to be the most intelligible were the same conditions that were perceived to be the noisiest. The perception of intelligibility and noisiness depended on the interaction of hearing aid manufacturer and noise reduction setting (p.001, effect size=.77) for hearing aids with WN + NR and depended on both hearing aid manufacturer (p

Book Synopsis Development and Objective Perceptual Quality Assessment of Monaural and Binaural Noise Reduction Schemes for Hearing Aids by : Thomas Rohdenburg
Download or read book Development and Objective Perceptual Quality Assessment of Monaural and Binaural Noise Reduction Schemes for Hearing Aids written by Thomas Rohdenburg and published by . This book was released on 2008 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: People with hearing impairment have great difficulties communicating in noisy and reverberant environments. They usually require a higher signal-to-noise ratio (SNR) to achieve the same listening performance as normal hearing people. The current dissertation addresses this difficulty with the development of novel binaural noise reduction schemes for hearing aids and their evaluation under realistic conditions. Particular consideration is given to influences of head shadow and diffraction, head movements, microphone properties, and the preservation of binaural information. The algorithms are evaluated using novel objective measures based on recent knowledge of the auditory system and by subjective listening tests. From the results it is expected that both, the algorithms and objective assessment methods, will prove to be beneficial for human communication in noise in the future. engl.

Book Synopsis Noise Reduction in Speech Processing by : Jacob Benesty
Download or read book Noise Reduction in Speech Processing written by Jacob Benesty and published by Springer Science & Business Media. This book was released on 2009-04-28 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: Noise is everywhere and in most applications that are related to audio and speech, such as human-machine interfaces, hands-free communications, voice over IP (VoIP), hearing aids, teleconferencing/telepresence/telecollaboration systems, and so many others, the signal of interest (usually speech) that is picked up by a microphone is generally contaminated by noise. As a result, the microphone signal has to be cleaned up with digital signal processing tools before it is stored, analyzed, transmitted, or played out. This cleaning process is often called noise reduction and this topic has attracted a considerable amount of research and engineering attention for several decades. One of the objectives of this book is to present in a common framework an overview of the state of the art of noise reduction algorithms in the single-channel (one microphone) case. The focus is on the most useful approaches, i.e., filtering techniques (in different domains) and spectral enhancement methods. The other objective of Noise Reduction in Speech Processing is to derive all these well-known techniques in a rigorous way and prove many fundamental and intuitive results often taken for granted. This book is especially written for graduate students and research engineers who work on noise reduction for speech and audio applications and want to understand the subtle mechanisms behind each approach. Many new and interesting concepts are presented in this text that we hope the readers will find useful and inspiring.

Book Synopsis Noise Reduction in Digital Hearing Aids with a Background of Environmental Sounds by : Lori Ann Summe
Download or read book Noise Reduction in Digital Hearing Aids with a Background of Environmental Sounds written by Lori Ann Summe and published by . This book was released on 2003 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Noise reduction in digital hearing aids is often tested using speech-weighted noise. Environmental sounds such as rain or an oscillating fan can also be used to determine the efficacy of noise reduction algorithms. The algorithms of four digital hearing aids were examined in the presence of five environmental sounds. Methods: Cool Edit 2000 was used to analyze the speech spectrum before and after noise reduction. The FAAF test was used as the speech sample. Recorded versions of a fan, a 727, ocean waves, rain, and a subway served as background sounds. The Natura, Signia, Lumina, and Danalogic hearing aids were used to compare noise reduction algorithms. Results: Noise reduction algorithms did not attenuate environmental sounds as well as they reportedly attenuated speech-weighted babble, in three of the four hearing aids tested. Only one hearing aid effectively attenuated the environmental sounds tested to an acceptable degree.
