A Simulation Study on Binaural Dereverberation and Noise Reduction based on Diffuse Power Spectral Density Estimators
Enhancement techniques in binaural hearing aids are crucial to improve speech understanding for hearing impaired persons in reverberation and noise. Since reverberation and noise can be commonly modeled as diffuse sound fields, many state-of-theart techniques require an estimate of the diffuse power spectral density (PSD). In this paper we evaluate the performance of binaural dereverberation an...
متن کاملDevelopment and Objective Perceptual Quality Assessment of Monaural and Binaural Noise Reduction Schemes for Hearing Aids
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. But even for normal hearing people a noise reduction is desirable in these environments, especially when using modern communication systems such as mobile phones, ...
متن کاملReal-time multiband dynamic compression and noise reduction for binaural hearing aids.
A multi-signal-processor set-up is introduced that is used for real-time implementation of digital hearing aid algorithms that operate on stereophonic (i.e., binaural) input signals and perform signal processing in the frequency domain. A multiband dynamic compression algorithm was implemented which operates in 24 critical band filter channels, allows for interaction between frequency bands and...
متن کاملNoise Reduction Schemes for Digital Hearing Aids and their Use for the Hearing Impaired
The aim of this thesis is to improve both the assessment methods and the available algorithms for noise reduction in hearing aids. In particular, the whole development chain from the construction of algorithms, subjective assessment of algorithmic performance by normal-hearing and hearing-impaired listeners as well as objective assessment methods is considered. The speech pause detection algori...
متن کاملPerformance comparison of binaural beamforming and MWF-based noise reduction algorithms for hearing aids
Noise reduction algorithms in hearing aids are crucial to improve speech understanding in background noise for hearing-impaired persons. For binaural hearing aids multi-microphone algorithms, exploiting signals from both the left and the right hearing aid, are considered to be promising techniques for noise reduction, because in addition to spectral information spatial sound information can be ...
