Active wind noise detection and suppression techniques are a new and essential paradigm for enhancing ASR-based functionality with smart glasses, in addition to other wearable and smart devices in the broader IoT (Internet of things). In this paper, we develop two separate algorithms for wind noise detection and suppression, respectively, operational in a challenging, low-energy regime. Togethe...

In this paper an application of the noise cancelling method for suppression of noise of a microphone array system is discussed. First an overview of the noise cancelling approach is given. This is followed by a description of the employment of the method in a realized microphone array system. The limiting factors are described and theoretical limits of the noise suppression are derived. Experim...

This paper attempts to make the public/workplace environment more pleasant by combining techniques of active noise control (ANC) and the limited ability of the human auditory system to register a sound in the vicinity of another sound of sufficiently higher intensity. The paper examines the limitations of ANC and masking techniques, and proposes a way to integrate these techniques. A process fo...

A novel impulsive noise elimination filter, entitled noise exclusive filter (NEF), which shows a high performance at the restoration of images distorted by impulsive noise, is proposed in this paper. NEF uses chi-square goodness-of-fit test in order to detect the corrupted pixels more accurately. Simulation results show that the proposed filter achieves a superior performance compared with the ...

This contribution is devoted to the noise suppression system for monoaural SPEAK-type cochlear implants. The system is based on the combination of the superdirective two-microphone array and the noise suppression post-processing, both implemented in the frequency domain. The relative insensitivity of the two-microphone superdirective system to the spectral magnitude di erences in both channels ...
