Modal analysis and acoustic noise characterization of a grain crusher
Annals of Agricultural and Environmental Medicine, 2018 Introduction Noise is one of the most important physical factors occurring in private farmers’ working environment. Hazardous noise exposures and hearing loss have been documented among farmers and farm workers for many years. In most cases, reducing the

A Minimal Metric for the Characterization of Acoustic Noise Emitted by Underwater Vehicles [PDF]
Sensors, 2020 Underwater robots emit sound during operations which can deteriorate the quality of acoustic data recorded by on-board sensors or disturb marine fauna during in vivo observations. Notwithstanding this, there have only been a few attempts at characterizing the acoustic emissions of underwater robots in the literature, and the datasheets of commercially ...

Characterization and Noise Analysis of Capacitive MEMS Acoustic Emission Transducers [PDF]
2007 IEEE Sensors, 2007 Resonant type capacitive MEMS transducers were fabricated using a multi-user MEMS process (MUMPs) for the detection of acoustic emission (AE). Electrical and mechanical characterization of the MEMS transducers has been performed. The performance of the transducers is limited by the noise.

Statistical Characterization and Modeling of Noise Effects in Near-Ultrasound Aerial Acoustic Communications [PDF]
Journal of the Acoustical Society of America, 2018 In this paper, the statistical properties of near-ultrasound acoustic noise in typical indoor environments are investigated. The results indicate that near-ultrasound noise exhibits impulsive behavior and that its first-order probability density functions can be accurately modeled by using a Gaussian mixture or symmetric alpha-stable (SαS ...
