Comparison of adaptive noise reduction algorithms in dual microphone hearing aids q
In this paper, a physical and perceptual evaluation of two adaptive noise reduction algorithms for dual-microphone hearing aids are described. This is the first comparison between a fixed directional microphone on the one hand, and an adaptive directional microphone and an adaptive beamformer on the other hand, all implemented in the same digital hearing aid. The adaptive directional microphone...
متن کاملComparison of adaptive noise reduction algorithms in dual microphone hearing aids
In this paper, a physical and a perceptual evaluation of two adaptive noise reduction algorithms for digital hearing aids is described. This is the rst comparison between a xed microphone pattern, an adaptive directionalmicrophone and an adaptive beamformer,which are implemented in the same hearing aid.
متن کاملTwo-Microphone Noise Reduction Using Spatial Information-Based Spectral Amplitude Estimation
Traditional two-microphone noise reduction algorithms to deal with highly nonstationary directional noises generally use the direction of arrival or phase difference information. The performance of these algorithms deteriorate when diffuse noises coexist with nonstationary directional noises in realistic adverse environments. In this paper, we present a two-channel noise reduction algorithm usi...

Introduction: Nominal noise reduction rate of the earmuff manufacturers can be different compared with the actual attenuation rate. The present study aimed to determine the actual noise reduction rate of common hearing protection devices using microphone in real ear method. Materials and Methods: In this study, five brands of common earmuffs used in Iranian industries were investigated on 30...
متن کاملSoft decision combining for dual channel noise reduction
We present a flexible dual channel noise reduction algorithm that combines the information of two microphone channels in the discrete Fourier transform domain. This algorithm can cope with substantially different signal-to-noise ratios at different timefrequency bins in both channels. The output is obtained by combining the outputs of two single channel filters and a dual channel filter weighte...
