Modulation-Based Digital Noise Reduction for Application to Hearing Protectors to Reduce Noise and Maintain Intelligibility
OBJECTIVE The objective of this study was to test the effects of modulation-based digital noise reduction (MB-DNR) on noise levels, speech intelligibility, and listening preference in four real-world noises. BACKGROUND A significant challenge in hearing protection device (HPD) design is to reduce ambient noise levels while maintaining users' ability to understand speech. MB-DNR technology, cu...
متن کاملSpeech Intelligibility of Cochlear-Implanted and Normal-Hearing Children
Introduction: Speech intelligibility, the ability to be understood verbally by listeners, is the gold standard for assessing the effectiveness of cochlear implantation. Thus, the goal of this study was to compare the speech intelligibility between normal-hearing and cochlear-implanted children using the Persian intelligibility test. Materials and Methods: Twenty-six cochlear-implanted childre...
متن کاملEstimating the Performance of Sound Restoration Hearing Protectors by Using the Speech Intelligibility Index
Despite advances in engineering noise controls and the use of administrative controls, miners are still dependent on hearing protection devices for prevention of noise-induced hearing loss. However, miners often raise concerns about the audibility of spoken communication when wearing conventional hearing protectors. Electronic technologies that selectively process and restore sounds from outsid...
متن کاملSpeech Perception in Noise with Active and Passive Hearing Protectors: Acoustical Analysis
This research project has compared the speech recognition scores for test fragments recorded in different kinds of realistic industrial noise, with both standard and active earplugs. The standard protectors block the incoming sound whereas the active work level-dependent. Acoustical analyses reveal the importance of global input sound pressure levels, especially for speech recognition with stan...
متن کاملSpeech recognition in noise with active and passive hearing protectors: a comparative study.
The perceived negative influence of standard hearing protectors on communication is a common argument for not wearing them. Thus, "augmented" protectors have been developed to improve speech intelligibility. Nevertheless, their actual benefit remains a point of concern. In this paper, speech perception with active earplugs is compared to standard passive custom-made earplugs. The two types of a...
