Objective Perceptual Quality Measures for the Evaluation of Noise Reduction Schemes
نویسندگان
چکیده
In this study, different objective quality measures for the performance prediction of noise reduction schemes are compared to subjective data from psychoacoustic listening tests. It is shown that the considered perceptual measures are appropriate to define a quality test-bench which can be used for the development and optimization of noise reduction schemes.

Subband-based Parameter Optimization in Noise Reduction Schemes by Means of Objective Perceptual Quality Measures
In general, noise reduction schemes for application in hearingaids or car environments have parameters that are determined by technical distance measures or heuristically based on informal listening by the algorithm developers. In [1] we have shown that quality measures based on psychoacoustic models are better suited to optimize single parameters in terms of the best subjective overall quality...
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 کاملRobustness analysis for multi-channel hearing aid algorithms with binaural output by means of objective perceptual quality measures
Introduction According to the ITU-T P.835 recommendation, subjective quality evaluation of noise reduction schemes involves (i) the perceived quality of the speech signal, (ii) the quality of the background signal and (iii) the overall quality. In [7] it has been shown that these subjective measures are predictable by objective measures in the case of monaural noise reduction schemes. In this s...

متن کاملEffect of Varied Gradation Levels of Noise Reduction Algorithm on Speech Perception through Acoustical and Perceptual Measures
Purpose: The purpose of the study was to evaluate the effect of different gradations of noise reduction (NR) algorithm in hearing aids, through acoustical and perceptual measures. Methods: The output of the hearing aid with NR at three gradations (minimum, medium and maximum) and without NR, at 0 dB signal to noise ratio (SNR) across three types of noise (cafeteria, speech babble, and traffic n...
