Low Delay Noise Reduction and Dereverberation for Hearing Aids
A new system for single-channel speech enhancement is proposed which achieves a joint suppression of late reverberant speech and background noise with a low signal delay and low computational complexity. It is based on a generalized spectral subtraction rule which depends on the variances of the late reverberant speech and background noise. The calculation of the spectral variances of the late ...
متن کاملMulti-channel algorithms for wind noise reduction and signal compensation in binaural hearing aids
This paper contains a new approach for wind noise reduction in binaural hearing aids. This approach combines the ”single-channel low frequency reduction” algorithm [1] and the ”two-channel correlation detector” [2] with a multi-channel binaural hearing aid to compensate the desired signal. The algorithm benefits from the fact that if wind comes from one side, the wind noise mostly occurs in the...
متن کاملPreservation of Localization Cues in BSS-Based Noise Reduction: Application in Binaural Hearing Aids
For speech applications, blind source separation provides an efficient strategy to enhance the target signal and to reduce the background noise in a noisy environment. Most ICA-based blind source separation (BSS) algorithms are designed under the assumption that the target and interfering signals are spatially located. When the number of interfering signals is small, one of the BSS outputs is e...
متن کاملCombined Noise Reduction and Coherence Reshaping for Binaural 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, algorithms that exploit the microphone 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 information can be exploit...
متن کاملReduced-bandwidth Multi-channel Wiener Filter based binaural noise reduction and localization cue preservation in binaural hearing aids
Binaural hearing aids allow for a wireless exchange of microphone signals between a left and a right device. A significant noise reduction performance improvement can be achieved compared to a monaural configuration (a single device) or a bilateral configuration (in which the devices work independently). In addition, the binaural localization cues, i.e. the Interaural Time Differences and Inter...
